A Low-Power and Low-Noise Amplifier for 3-5GHz UWB Applications

Abstract

This paper presents a common gate low-power low noise amplifier (LNA) for DS-UWB low-band and MB-OFDM group-A ultra-wideband radio system. The LNA is designed and implemented in 0.18 mum RF CMOS process. Simulation results show that power gain of 15.4 dB, input and output matching lower than -10.6 dB and -13.3 dB, and a minimum NF of 3.8 dB can be achieved, while the power consumption is only 3.24 mW through 1.8 V power supply
