Abstract

A multi-stage low-noise amplifier (LNA) with LC-tank load to extend the bandwidth is designed for ultra-wideband (UWB) wireless receiver. The design consists of three LC-tank cascode amplifier and one output buffer and is implemented in 0.18 um RF CMOS process. The LNA gives 14.5 dB gain and 7.2 GHz 3 dB bandwidth (3.1-10.3 GHz) while consuming 22.8 mW through a 1.5 V supply. Over the 3.1 GHz-10.3 GHz frequency band, a minimum noise figure of 2.6 dB and input return loss lower than -8.8 dB have been achieved.
