Nova konfiguracija širokopojasnog nisko-šumnog pojačavača u CMOS tehnologiji / А new design of ultra-wideband low noise amplifier in CMOS technology

Description

<p>Nisko-šumni pojačavač (NŠP) nalazi se u prijemnom delu bežičnog<br />primopredajnika neposredno nakon antene. NJegova uloga je da ulazni<br />signal određene frekvencije i male snage izdvoji i pojača iznad nivoa<br />šuma prijemnika. U okviru doktorske disertacije prikazane su i<br />opisane metode za projektovanje širokopojasnih (UWB) NŠP u CMOS<br />tehnologiji. Ukupno je predloženo devet novih konfiguracija NŠP. Na<br />osnovu dobijenih rezultata, u 0,18 &mu;m UMC CMOS tehnologiji<br />realizovan je i fabrikovan NŠP jednostavne topologije, koja<br />predstavlja zbir dva pristupa, pojačavačkog stepena kaskodne<br />strukture sa povratnom spregom i stepena sa višestrukim<br />iskorišćenjem struje. NŠP je projektovan za frekvencijski opseg od<br />3,1 do 5 GHz. Takođe, opisana je metoda za merenje parametara NŠP, a<br />zatim je i izvršena njegova karakterizacija.</p> / <p>In the transceiver chain the low noise amplifier (LNA) is placed in the frontend<br />of the receiver after the antenna. The LNA needs to isolate and amplify<br />received weak signal at a specific frequency above the noise level of the<br />receiver. In the scope of this doctoral dissertation methods for designing<br />ultra-wideband (UWB) LNA in CMOS technology are presented and<br />described. Nine new LNA configurations were proposed. Based on the<br />obtained results, simple LNA configuration, obtained by merging casode<br />feedback topology and current-reuse technique, was realized and fabricated<br />in 0.18 &mu;m UMC CMOS technology. The LNA is designed for the frequency<br />band from 3.1 to 5 GHz. In addition, the method for measurement LNA<br />parameters is described and the proposed LNA was characterized.</p>
