Ce travail s’inscrit dans un projet consistant à développer un prototype de capteur RF autonome et intelligent permettant la réalisation d’un réseau de capteurs sans fil dans un environnement industriel. Cette thèse traite de l’étude, la conception et la réalisation de la partie radiofréquence de la chaîne d’émission sans fils du capteur RF dans la bande ISM 863-870 MHz en technologie CMOS AMS 0.35µm. Cette chaîne inclut toutes les fonctions depuis l’oscillateur local jusqu’à l’amplificateur de puissance. L’émetteur occupe une surface de 0.22mm² et consomme environ 27mA sous une tension d’alimentation de 3.3V. De nombreux principes innovants ont été mis en œuvre et validés. Tous ces principes peuvent être facilement transposés à d’autres standards de communication et dans d’autres bandes de fréquences. Les résultats de simulations du dessin des masques vérifient complètement les spécifications et confirment les simulations. Une caractérisation expérimentale partielle valide les nouvelles architectures proposées. / This work joins in a project consisting in developing prototype of an autonomous and smart RF sensor allowing the realization of a wireless sensor network in an industrial environment. This thesis deals with the study, the design and the realization of the radio-frequency part of the transmitter using the 863-870 MHz ISM band and the CMOS AMS 0.35µm technology. This transmitter includes all the functions from the local oscillator to the power amplifier. The integrated circuit occupies a surface of 0.22mm² and consumes approximately 27mA under a supply voltage of 3.3V. Numerous innovative principles were implemented and validated. All these principles can be easily transposed into other standards of communication and in other frequency bands. The results of the post-layout simulation completely satisfy the specifications and confirm the simulations. Partial experimental characterization validates new architectures proposed.

This diploma thesis deals with processes of electrical circuits calculations in the last years' worldwide standards like Dymola, MATLAB, Maple or SPICE applications. Circuits calculations are linked with methods for solving linear differential equations, used in this work also by verification of functionality of designed models for CMOS inverter, CMOS NAND, CMOS NOR. Numerical integration method in combination with Taylor series is a suitable method also for parallel calculations of CMOS VLSI circuits. CMOS circuits simulation was implemented with this method in applications in MATLAB language, solving circuits, represented by differential equations. Functionality of the applications was verified by some real examples. Significant acceleration of calculations using Taylor series compared to other methods is an important factor in choosing methods used in circuit simulations.
