The place where the internet is the main instrument for people to relate, interacts, consume, have fun and be informed. On the other side, almost an island from this technological trend, a space in which oral communication, trust, the value of the word, know the neighborhood and community are what prevails. It is more a phenomenon due to the growth of Class C in Brazil, after the launch of the Real Plan, by Fernando Henrique Cardoso government of former President Itamar Franco, and the implementation of social measures in subsequent years in the Luiz Inácio Lula da Silva government. The segment that represents 54% of the population and companies is a new frontier of business. Through literature search and document analysis for content analysis, this single case study will investigate how Banco Itaú communicates with these stakeholders to provide microcredit in the outskirts of São Paulo. In a world where we think the faster sensory and information technology will be in the future the oral communication can lead to important knowledge when we want to communicate with the Base of the Pyramid. / Por um lado, o mundo do Século XXI com ferramentas que possibilitam cada vez mais estarmos conectados e dependentes das tecnologias de comunicação, em que a internet prevalece como meio principal para as pessoas se relacionarem, interagirem, consumirem, se divertirem e se informarem. Do outro lado, quase que uma ilha à parte dessa tendência tecnológica, um espaço em que a comunicação oral, a confiança, o valor da palavra, o conhecer o vizinho do bairro e a comunidade são o que prevalece. Trata-se de mais um fenômeno decorrente do crescimento da Classe C no Brasil, posterior ao lançamento do Plano Real, por Fernando Henrique Cardoso no governo do ex-presidente Itamar Franco, e da implantação de medidas sociais nos anos seguintes, durante o governo de Luiz Inácio Lula da Silva. O segmento que representa 54% da população brasileira e desperta a atenção das empresas como uma nova frente de geração de riquezas e negócios. Por meio de pesquisa bibliográfica e análise documental para análise de conteúdo, este estudo de caso único investigará como o Banco Itaú se comunica com esse público para oferecer o microcrédito na periferia da cidade de São Paulo. Num mundo em que se pensa quanto mais rápidas e sensoriais serão as tecnologias de informação no futuro, o bom e velho bate-papo pode levar a conhecimentos importantes quando queremos nos comunicar com as camadas populares da população.

A presente pesquisa pretende estudar aspectos da midiatização do consumo e do sentido de classe social na telenovela com foco na representação do que vem sendo considerada a \"nova classe C\" ou \"nova classe média\" brasileira. Para tanto, analisou-se cenas das telenovelas Avenida Brasil (2012), de João Emanuel Carneiro, e Cheias de Charme (2012), de Filipe Miguez e Izabel de Oliveira. Ambas exibidas na Rede Globo, a primeira no horário das 21 horas e a segunda às 19 horas. As duas foram consideradas pela mídia como tramas que representam a \"nova classe C\", o que justifica a escolha. Inicialmente, o trabalho traz uma breve discussão teórica sobre o termo midiatização, sobre as concepções sociológicas de classe social e os estudos realizados sobre telenovela e classe. Pretende-se, assim, problematizar a expressão \"nova classe C\", de modo a entender sua natureza e validade sociológica, bem como levantar a forma como a telenovela costuma retratar as classes sociais, para, assim, rumar às análises com embasamento teórico. A metodologia de análise se fundamenta na concepção marxista de materialismo histórico e dialética, com a qual estão relacionadas as teorias do filósofo da linguagem Mikhail Bakhtin, a Análise do Discurso Francesa e a Análise do Discurso Crítica. Essas teorias tiveram alguns de seus elementos mesclados e utilizadas como protocolo metodológico. A partir do protocolo e dos levantamentos teóricos sobre classes sociais e telenovela, objetiva-se averiguar as nuanças da midiatização do consumo e do sentido de classe social na representação discursiva do que vem sendo chamada a \"nova classe C\" em cenas selecionadas de Avenida Brasil e Cheias de Charme. Com as análises das cenas que retratam situações que aludem ao consumo, obtivemos resultados que apontam para o fato de ambas as telenovelas, em diferentes graus, apresentarem em seus discursos características que condizem com o modo próprio da telenovela tratar as classes sociais, assim como elementos que se relacionam com uma visão social hegemônica, além de aspectos que estão conectados com a realidade comentada pelos sociólogos e que também indicam mudanças na forma usual das telenovelas retratarem as diferenças sociais. Ademais, de acordo com o conceito de midiatização e com o papel da telenovela no Brasil, acreditamos que essas representações contribuem para a formação de um conhecimento social do que seria a \"nova classe C\" brasileira. / This search aims to study aspects of the mediatization of consumption and the sense of social class in telenovela, with focus on what is dubbed \"the new class C\" or \"new middle class\" in Brazil. For that purpose, it was analyzed scenes of the telenovelas Avenida Brasil (2012), by João Emanuel Carneiro, and Cheias de Charme (2012), by Filipe Miguez and Izabel de Oliveira. Both were aired in Rede Globo, at 9pm. and 7pm., respectively. These two productions were considered by the media as representative of the \"new class C\", which justifies the choice. Initially, this work brings a brief theoretical discussion about the mediatization concept, about the sociologic concept of social class and the studies which cover telenovela and social class altogether. It is intended, therefore, to problematize the expression \"new class C\", in order to understand its origin and sociologic nature, as well as to look at the manner by which the telenovela usually portrays the social classes, so as to produce an analysis which has theoretical base. The methodology to analyze the matter is based on the Marxist conception of dialectic and in the historical materialism, which are related to the theories of the Russian language philosopher Mikhail Bakhtin, the French Discourse Analysis and Critical Discourse Analysis. These theories had some of their elements combined and used as methodological protocol. From methodological protocol and from the theoretical points about social classes and telenovelas, the objective is to investigate the nuances of the mediatization of consumption and the sense of social class in the discursive representations of the dubbed \"new class C\" in scenes picked from Avenida Brasil and Cheias de Charme. Based on the analysis of scenes that portray situations that allude to consumption, we obtained results which demonstrate that both telenovelas, yet in different degrees, reveal in their plots characteristics that connect with the particular view with which the telenovela approaches the social classes, as well as with elements that are related with the hegemonic social view, apart from aspects that are connected with the reality commented by sociologists and which indicates changes in the usual way that the telenovela portrays the social differences. Moreover, according to the concept of mediatization as well as to the role of telenovela in Brazil, we believe that those representations contribute to the making of a social knowledge of what the new Brazilian \"new class C\" would be.

A pesquisa analisa o consumo cultural (especialmente de rádio e televisão) de um grupo de empregadas domésticas que trabalham na cidade de São Paulo. Por meio de um mapeamento das preferências culturais dessas trabalhadoras organizadas nos perfis românticas, descoladas e evangélicas , discuto a importância dessas mídias no universo estudado. Paralelamente, a partir da análise de representações das empregadas domésticas na televisão, em especial, por meio da uma análise compartilhada da telenovela Cheias de Charme (Globo, 2012, 19h30), avalio as transformações ocorridas na imagem da empregada doméstica na ficção e na vida real , explorando a passagem de trabalhadora pobre para consumidora da classe C. Nesse contexto, temáticas como trabalho doméstico, gênero, classe, cor, consumo e mídias são relacionadas. / The research analyses the cultural consumption (particularly television and radio) of domestic workers in São Paulo (SP). Through mapping the cultural preferences of these women workers divided in three profiles, romantic, up to date and evangelic I raise reflections on the importance of these media among them. In parallel, through the analyses of domestic workers representations in television, in particular in the telenovela Cheias de Charme (Globo, 2012, 19h30), I discuss the transformations on the image of these workers in fiction and in real life exploring the passage from poor workers to class C consumers. In this context, issues such as domestic labor, gender, class, race, consumption and media are interrelated.

[pt] Esta dissertação buscou contribuir para análise de como os consumidores da classe C consomem shopping centers. Para alcançar tal objetivo, primeiramente foi revisada a literatura sobre Consumer Culture Theory para proporcionar um contexto relativo à análise, depois estudou-se o consumo no segmento de baixa renda, especificamente o conceito de Nova Classe Média (classe C), segundo Neri (2008), e suas implicações para o comportamento do consumidor. Adicionalmente, buscou-se entender na literatura a questão sobre o comportamento dos consumidores da baixa renda, especificamente da classe C, com relação aos shopping centers. Foram conduzidas 22 entrevistas em profundidade com entrevistados em quatro shopping centers da região metropolitana do Rio de Janeiro, todos tendo como público principal consumidores de baixa renda. Na análise dos dados, foram estudadas as entrevistas de membros da classe C, sendo codificadas utilizando o programa Atlas-ti. Os temas e descrições foram relacionados com a teoria fundamentada para, então, se chegar a interpretações dos significados dos mesmos. Os principais achados foram: é mais importante frequentar o shopping para os entrevistados que a compra no shopping; apesar da preferência pelo ambiente do shopping, os entrevistados demonstraram maior intenção de compra nos ambientes varejistas de rua; a internet influenciou mudanças no comportamento dos consumidores da classe C em relação aos shopping centers; e mesmo tendo a expectativa de não reduzir a frequência de idas ao shopping devido à redução de renda, os consumidores da classe C acabaram frequentando menos os shopping após uma redução de renda. / [en] This study sought to contribute to the understanding of how class C consumers consume malls. Firstly, in order to achieve this goal, literature on Consumer Culture Theory was reviewed to provide context to the analysis. Then, consumption by the low-income segment, specifically the New Middle Class (class C), according to Neri (2008), was studied and its implications on consumer behavior. In addition, available literature regarding the behavior of low-income consumers, specifically of class C consumers, with respect to shopping malls was analyzed. A total of 22 in-depth interviews were conducted with respondents in four shopping malls in the metropolitan area of Rio de Janeiro, all having as main target segment low-income consumers. In data analysis, interviews from class C consumers were studied and encoded using the Atlas-ti software. The themes and reports were related to the contextual theory to then arrive at interpretations of the meanings of such accounts. The main findings were: visiting the mall was more important than buying in the malls, as purchase intent in street retail environments was higher than in malls despite the preference for shopping environment; the internet has influenced changes in class C consumer behavior with respect to shopping malls; and even though the expectation of consumers is that their mall visitation frequency will not be reduced as a result of a decrease in income, class C consumers ended up reducing the amount of visits to the mall after an actual income reduction.

Fly ash and blast furnace slag are the two major industrial solid by-products generated in most countries including India. Although their utilization rate has increased in the recent years, still huge quantities of these material remain unused and are stored or disposed of consuming large land area involving huge costs apart from causing environmental problems. Environmentally safe disposal of Fly ash is much more troublesome because of its ever increasing quantity and its nature compared to blast furnace slag. Bulk utilization of these materials which is essentially possible in civil engineering in general and more particular in geotechnical engineering can provide a relief to environmental problems apart from having economic benefit. One of the important aspects of these waste materials is that they improve physical and mechanical properties with time and can be enhanced to a significant level by activating with chemical additives like lime and cement. Class-C Fly ashes which have sufficient lime are well utilized but class-F Fly ashes account for a considerable portion that is disposed of due to their low chemical reactivity. Blast furnace slag in granulated form is used as a replacement for sand to conserve the fast declining natural source. The granulated blast furnace slag (GBS) is further ground to enhance its pozzolanic nature. If GBS is activated by chemical means rather than grinding, it can provide a good economical option and enhance its utilization potential as well. GGBS is latent hydraulic cement and is mostly utilized in cement and concrete industries. Most uses of these materials are due to their pozzolanic reactivity. Though Fly ash and GGBS are pozzolanic materials, there is a considerable difference in their chemical composition. For optimal pozzolanic reactivity, sufficient lime and silica should be available in desired proportions. Generally, Fly ash has higher silica (SiO2) content whereas GGBS is rich in lime (CaO) content. Combining these two industrial wastes in the right proportion may be more beneficial compared to using them individually. The main objective of the thesis has been to evaluate the suitability of the class-F Fly ash/GGBS mixtures with as high Fly ash contents for Geotechnical and Geo-environmental applications. For this purpose, sufficient amount of class-F Fly ash and GGBS were collected and their mixtures were tested in the laboratory for analyzing their mechanical behavior. The experimental program included the evaluation of mechanical properties such as compaction, strength, compressibility of the Fly ash/GGBS mixtures at different proportions with GGBS content varying from 10 to 40 percent. An external agent such as chemical additives like lime or cement is required to accelerate the hydration and pozzolanic reactions in both these materials. Hence, addition of varying percentages of lime is also considered. However, these studies are not extended to chemically activate GBS and only GGBS is used in the present study. Unconfined compressive strength tests have been carried out on various Fly ash/ GGBS mixtures at different proportions at different curing periods. The test results demonstrated rise in strength with increase in GGBS content and with 30 and 40 percent of GGBS addition, the mixture showed higher strength than either of the components i.e. Fly ash or GGBS after sufficient curing periods. Addition of small amount of lime increased the strength tremendously which indicated the occurrence of stronger cementitious reactions in the Fly ash/GGBS mixtures than in samples containing only Fly ash. Improvement of the strength of the Fly ash/GGBS mixtures was explained through micro-structural and mineralogical studies. The microstructure and mineralogical studies of the original and the stabilized samples were investigated by scanning electron microscopy (SEM) and X-Ray diffraction techniques respectively. These studies together showed the formation of cementitious compounds such as C-S-H, responsible for imparting strength to the pozzolanic materials, is better in the mixture containing 30 and 40 percent of GGBS content than in individual components. Resilient and permanent deformation behavior on an optimized mix sample of Fly ash and GGBS cured for 7 day curing period has been studied. The Resilient Modulus (Mr) is a measure of subgrade material stiffness and is actually an estimate of its modulus of elasticity (E). The permanent deformation behavior is also important in predicting the performance of the pavements particularly in thin pavements encountered mainly in rural and low volume roads. The higher resilient modulus values indicated its suitability for use as subgrade or sub-base materials in pavement construction. Permanent axial strain was found to increase with the number of load cycles and accumulation of plastic strain in the sample reduced with the increase in confining pressure. Consolidation tests were carried on Fly ash/GGBS mixtures using conventional oedometer to assess their volume stability. However, such materials develop increased strength with time and conventional rate of 24 hour as duration of load increment which requires considerable time to complete the test is not suitable to assess their volume change behavior in initial stages. An attempt was thus made to reduce the duration of load increment so as to reflect the true compressibility characteristics of the material as close as possible. By comparing the compressibility behavior of Fly ash and GGBS between conventional 24 hour and 30 minutes duration of load increment, it was found that 30 minutes was sufficient to assess the compressibility characteristics due to the higher rate of consolidation. The results indicated the compressibility of the Fly ash/GGBS mixtures slightly decreases initially but increase with increase in GGBS content. Addition of lime did not have any significant effect on the compressibility characteristics since the pozzolanic reaction, which is a time dependent process and as such could not influence due to very low duration of loading. Results were also represented in terms of constrained modulus which is a most commonly used parameter for the determination of settlement under one dimensional compression tests. It was found that tangent constrained modulus showed higher values only at higher amounts of GGBS. It was also concluded that settlement analysis can also be done by taking into account the constrained modulus. The low values of compression and recompression indices suggested that settlements on the embankments and fills (and the structures built upon these) will be immediate and minimal when these mixtures are used. In addition to geotechnical applications of Fly ash/GGBS mixture, their use for the removal of heavy metals for contaminated soils was also explored. Batch equilibrium tests at different pH and time intervals were conducted with Fly ash and Fly ash/GGBS mixture at a proportion of 70:30 by weight as adsorbents to adsorb lead ions. It was found that though uptake of lead by Fly ash itself was high, it increased further in the presence of GGBS. Also, the removal of lead ions increased with increase in pH of the solution but decreases at very high pH. The retention of lead ions by sorbents at higher pH was due to its precipitation as hydroxide. Results of the adsorption kinetics showed that the reaction involving removal of lead by both the adsorbents follow second-order kinetics. One of the major problems which geotechnical engineers often face is construction of foundations on expansive soils. Though stabilization of expansive soils with lime or cement is well established, the use of by-product materials such as Fly ash and blast furnace slag to achieve economy and reduce the disposal problem needs to be explored. To stabilize the soil, binder comprising of Fly ash and GGBS in the ratio of 70:30 was used. Different percentages of binder with respect to the soil were incorporated to the expansive soil and changes in the physical and engineering properties of the soil were examined. Small addition of lime was also considered to enhance the pozzolanic reactions by increasing the pH. It was found that liquid limit, plasticity index, swell potential and swell pressure of the expansive soil decreased considerably while the strength increased with the addition of binder. The effect was more pronounced with the addition of lime. Swell potential and swell pressure reduced significantly in the presence of lime. Based on the results, it can be concluded that the expansive soils can be successfully stabilized with the Fly ash-GGBS based binder with small addition of lime. This is also more advantageous in terms of lime requirement which is typically high when Fly ash, class-F in particular, is used alone to stabilize expansive soils. Based on the studies carried out in the present work, it is established that combination of Fly ash and GGBS can be advantageous as compared to using them separately for various geotechnical applications such as for construction of embankments/fills, stabilization of expansive soils etc. with very small amount of lime. Further, these mixtures have better potential for geo-environmental applications such as decontamination of soil. However, it is still a challenge to activate GBS without grinding.

The goal of this diploma's thesis is to create a design of a two stages amplifier working in a band reserved for the secondary surveillance radar at the frequency of 1090 MHz. Output power of the amplifier should be 20 W and efficiency should be as high as possible. Because of this the second stage is designed in class C. Contents of this diploma's thesis include a theoretical analysis, simulations of the amplifier parameters, comparison of the Ansys Designer and AWR Microwave Office simulation programs and design of both stages of the amplifier, followed by a comparison of the measured parameters with the simulations.

The Portland Cement Association commissioned a research project at Brigham Young University to compare selected laboratory durability tests available for assessing stabilized aggregate base materials. The laboratory research associated with this project involved two granular base materials, three stabilizers at three concentration levels each, and three durability tests in a full-factorial experimental design. The granular base materials consisted of an aggregate-reclaimed asphalt pavement blend obtained from Interstate 84 (I-84) and a crushed limestone obtained from U.S. Highway 91 (US-91), while the three stabilizer types included Class C fly ash, lime-fly ash, and Type I/II Portland cement. Specimens were tested for durability using the freeze-thaw test, the vacuum saturation test, and the tube suction test. Analyses of the test results indicated that the unconfined compressive strength (UCS) and retained UCS were higher for specimens tested in freeze-thaw cycling than the corresponding values associated with vacuum saturation testing. This observation suggests that the vacuum saturation test is more severe than the freeze-thaw test for materials similar to those evaluated in this research. The analyses also indicated that the I-84 material retained more strength during freeze-thaw cycling and vacuum saturation and exhibited lower final dielectric values during tube suction testing than the US-91 material. Although the I-84 material performed better than the US-91 material, the I-84 material required higher stabilizer concentrations to reach the target 7-day UCS values specified in this research. After freeze-thaw testing, the Class C fly-treated specimens were significantly stronger than both lime-fly ash- and cement-treated specimens. In the vacuum saturation test, none of the three stabilizer types were significantly different from each other with respect to either UCS or retained UCS. Dielectric values measured during tube suction testing were lowest for cement-treated specimens, indicating that cement performed better than other stabilizers in reducing the moisture/frost susceptibility of the treated materials. The results also show that, as the stabilizer concentration level increased from low to high, specimens performed better in nearly all cases. A strong correlation was identified between UCS after the freeze-thaw test and UCS after the vacuum saturation test, while very weak correlations were observed between the final dielectric value after tube suction testing and all other response variables. Differences in variability between test results were determined to be statistically insignificant. Engineers interested in specifying a comparatively severe laboratory durability test should consider vacuum saturation testing for specimens treated with stabilizers similar to those evaluated in this research. The vacuum saturation test is superior to both the freeze-thaw and tube suction tests because of the shorter duration and lack of a need for daily specimen monitoring. Although the Class C fly ash used in this research performed well, further investigation of various sources of Class C fly ash is recommended because of the variability inherent in that material. Similar research should be performed on subgrade soils, which are also routinely stabilized in pavement construction. Research related to long-term field performance of stabilized materials should be conducted to develop appropriate thresholds for laboratory UCS values in conjunction with vacuum saturation testing.

Soit p un nombre premier. Les résultats de cette thèse s'inscrivent dans le cadre du programme de Langlands p-adique. Lorsque V est une représentation p-adique de dimension 2 du groupe Gal(\bar{Qp}/Qp), on sait lui associer une représentation p-adique continue B(V) de GL₂(Qp). Si F est une extension finie non triviale de Qp, la question d'associer des représentations p-adiques de GL₂(F) aux représentations p-adiques de dimension 2 de Gal(\bar{Qp}/F) dans l'esprit d'une correspondance locale à la Langlands s'annonce beaucoup plus délicate. Dans ce texte, nous considérons des espaces de Banach p-adiques, munis d'une action linéaire continue de GL₂(F), qui sont des complétions unitaires universelles de certaines représentations localement Qp-analytiques de GL₂(F). Celles-ci sont susceptibles de jouer un rôle important dans une éventuelle correspondance de Langlands locale p-adique pour GL₂(F). Le résultat principal de cette thèse est démontré dans le Chapitre 3 et généralise des résultats antérieurs de Berger et Breuil. Il consiste en une description explicite de ces complétés unitaires universels à l'aide des fonctions continues sur F d'un certain type. Pour ce faire, nous introduisons dans le Chapitre 2 des espaces de Banach de fonctions de classe C^r, où r est un nombre rationnel positif, et leurs espaces duaux de distributions d'ordre r. Nous construisons une base de Banach et nous donnons un critère de prolongement des formes linéaires définies sur un espace de fonctions localement Qp-polynomiales en distributions d'ordre r. Ce faisant, nous généralisons des résultats classiques dus à Amice-Vélu et Vishik. Dans le Chapitre 4, nous exhibons des cas de non nullité pour les complétions unitaires universelles considérées par construction explicite de réseaux invariants. Cela donne de nouveaux cas de la conjecture proposée par Breuil et Schneider sur l'équivalence entre l'existence de normes invariantes sur certaines représentations localement algébriques de GL_d(F) et l'existence de certaines représentations de de Rham de Gal(\bar{Qp}/F). / Let p be a prime. The subject of this thesis is the p-adic Langlands correspondence. If V is a p-adic representation of dimension 2 of the group Gal(\bar{Qp}/Qp), it is known how to associate to it a continuous p-adic representation B(V) of GL₂(Qp). If F is a non-trivial finite extension of Qp, the issue of associating p-adic representations of GL₂(F) to p-adic representations of dimension 2 of Gal(\bar{Qp}/F) in the spirit of a local Langlands correspondence appears much more delicate. In this text we consider a class of p-adic Banach spaces, endowed with a continuous linear action of GL₂(F), which are obtained as universal unitary completions of certain locally Qp-analytic representations of GL₂(F). Such representations are likely to play an important role in a future local p-adic Langlands correspondence for GL₂(F). The main result of this thesis is proved in Chapter 3 and generalizes some previous results of Berger and Breuil. It consists in an explicit description of these universal unitary completions by means of a certain class of continuous functions on F. In order to do this, we introduce in Chapter 2 a class of Banach spaces of functions of class C^r, where r is a positive rational number, as well as their dual spaces of distributions of order r. We build a Banach base and we give a criterion for telling when a linear form defined on a space of locally Qp-polynomial functions extends to a distribution of order r. As a consequence, we generalize some classical results due to Amice-Vélu and Vishik. In Chapter 4 we exhibit cases of non-nullity for these universal unitary completions, by an explicit construction of invariant lattices. This also provides new instances of the Breuil-Schneider conjecture about the equivalence between the existence of invariant norms on certain locally algebraic representations of GL_d(F) and the existence of certain De Rham representations of Gal(\bar{Qp}/F).

Following the rise of Internet of Things (IoT), or just the technological advancements and expectations in a world where the things are or will be connected, new demands are put on Integrated Circuit (IC) for wireless connectivity. The use cases seem endless; smart home, healthcare, entertainment, and science are all areas that can benefit from connectivity of low power electronics. But there are obstacles to overcome. Meeting the specifications, especially the phase noise requirements of modern high-speed wireless standards can be a challenge for devices that run on low supply voltages and are allowed only very limited power consumption. The focus of this thesis is the exploration of modern LC-oscillator architectures for RF-transceivers, and the design and post-layout evaluation of a Digitally Controlled Oscillator (DCO) intended to be used in an All-Digital Phase Locked Loop (ADPLL) in a 22 nm FD-SOI process. The DCO specifications are set by an ADPLL for the Wi-Fi 6 (MCS 11) standard. The ADPLL is replacing the blocks that are usually implemented as noise-sensitive analog components with more robust digital blocks that are easier to integrate with baseband- and digital-circuitry. A dual-core class-C oscillator with a dynamic-biasing circuit is proposed and designed to meet the specification of -121 dBc/Hz phase noise at a 1 MHz offset from 7.8 GHz, a –7.18.6 GHz tuning range, and a frequency resolution of at most 35 kHz around 7.8 GHz. The phase noise specification is met; a phase noise of -121 dBc/Hz at the 1 MHz offset from 7.8 GHz is achieved in post-layout simulation along with a Figure of Merit (FoM) of 189.9, and an average tracking frequency step of 5.8 MHz. The tuning range specification was not met, but it is reasonable to believe that the specified range can be met after some redesign of the capacitor banks. Further work will be required. / Till följd av tillväxten inom Internet of Things (IoT), eller bara de teknologiska framgångar och förväntningar på en värld där dem flesta saker är eller kommer att bli uppkopplade, ställs nya krav på Integrated Circuit (IC)-komponenter för trådlös uppkoppling. Tillämningsområdena är oändliga; smart home, sjukvård och hälsa, underhållning och forskning är områden som som kan dra nytta av nya uppkopplingsmöjligheter med extremt strömsnål elektronik. Att leva upp till specifikationerna för moderna trådlösa höghastighetsuppkopplingar, speciellt när det kommer till fasbrus, kan dock vara en utmaning för enheter som måste klara sig med en väldigt begränsad effektåtgång. Fokus för denna avhandling är design och utvärdering på schematik och layout-nivå av en Digitally Controlled Oscillator (DCO) för en 22 nm Fully Depleted Silicon-On-Insulator (FD-SOI)-process avsedd att klara specifikationen satt av en given All-Digital Phase Locked Loop (ADPLL) för Wi-Fi 6 (MCS 11) standarden. En DCO och ADPLL ersätter block som tidigare tillämpats som analoga bruskänsliga komponenter med robustare digitala komponenter som är enklare att integrera med bas-band och digital logik-kretsar. En dubbelkärnig klass-C DCO med en dynamisk biaskrets föreslås för att nå kravet på fasbrus på maximalt -121 dBc/Hz mätt vid 1 MHz från en frekvens på 7.8 GHz, med ett frekvensomfång 7.1-8.6 GHz och en frekvensupplösning under 35 kHz. Fasbruset vid denna 1 MHz från 7.8 GHz uppmättes i simulering till -121 dBc/Hz, och en Figure of Merit (FoM) på 189.9 har uppnåtts, samt en genomsnittlig frekvensupplösning på 5.8 MHz nära 7.8 GHz. Designen klarar inte av att möta kraven på frekvensomfång, men det är sannolikt att en liknande design kan möta specifikationen efter ytterligare revision. Ytterligare arbete krävs.
