Abstract

A CMOS low noise amplifier (LNA) with shunt feedback for RF front-end of 3-5 GHz OFDM ultra wideband (UWB) receiver was designed. The proposed LNA architecture with an additional source inductor was presented to improve its performance, the LNA has been simulated with TSMC 0.18μm standard RF CMOS process, and it has a noise figure of less than 1.9dB, power gain of 11dB at 4.3GHz at 1.8V power supply.
