A CMOS current reused low-noise amplifier for ultra-wideband wireless receiver

A current reused low-noise amplifier (LNA) with gain compensated to extend the bandwidth which is designed for ultra-wideband (UWB) wireless receiver. The design consists of two cascode common-source amplifier and an output buffer which is implemented in 0.18 um RF CMOS process. The LNA gives 13.1 dB gain; 9.1 GHz 3 dB bandwidth (3.1-12.2 GHz) while consuming 13.9 mW through a 1.8 V supply. Over the 3.1 GHz - 10.6 GHz frequency band, a minimum noise figure of 2.7 dB and input return loss lower than -8.7 dB have been achieved.
