摘要

设计了一种用于3 - 5ghz OFDM超宽带接收机射频前端的分流反馈CMOS低噪声放大器(LNA)。采用台积电0.18µm标准RF CMOS工艺对LNA进行了仿真，结果表明，该LNA在1.8V电源下，噪声系数小于1.9dB，功率增益为11dB，工作频率为4.3GHz。

Design of low noise amplifier with shunt feedback for 3–5 GHz UWB receiver

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.
