Abstract

This paper presents an ultra-wideband (UWB) CMOS low noise amplifier (LNA) topology that operates in 3.1-10.6GHz band. The common gate structure provides wideband input matching and flattens the passband gain. The proposed UWB amplifier is implemented in 0.18 um CMOS technology for lower band operation mode. Simulation shows a minimum NF of 2.35 dB, a power gain of $18.3{\sim}20\;dB$, better than -10 dB of input and output matching, while consuming 16.4 mW.
