Summary:
A current reused low-noise amplifier (LNA) with gain compensated to extend the bandwidth and 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 0.18um RF CMOS process. The LNA gives 13.1dB gain; 9.1GHz 3dB bandwidth (3.1-12.2GHz) while consuming 13.9mW through a 1.8V supply. Over the 3.1GHz - 10.6GHz frequency band, a minimum noise figure of 2.7dB and input return loss lower than -8.7dB have been achieved.
