A REVIEW OF 2-10 GHZ LNA IN STANDARD CMOS USING DIFFERENT TOPOLOGIES

LNA is the most important part of receiver system. For any LNA it is very essential to keep high gain with linearity and a low noise figure for its successive blocks in the system. This paper presents the literature review of various LNAs used for a frequency range from 2 GHz to 10 GHz. The most important parameters considered in a LNA are gain, noise figure, linearity and impedance matching. Current reuse, cascade amplifiers, cascoded amplifiers topology, source degeneration topology, resistive feedback, cross coupled capacitor technique, g_m-boosted current reuse topology, single stage, multistage are the defined techniques used for LNA design.
