Abstract

In this paper, a CMOS low-noise amplifier (LNA) is designed for ultra-wideband (UWB) wireless receiver system. The design consists of a wideband input impedance matching network, a cascoded amplifier with shunt-peaked load, a RLC-impedance feedback loop and an output buffer for measurement purpose. It is fabricated in TSMC 0.18 um standard RF CMOS process. The LNA gives 11.5 dB maximum power gain between 3.1 GHz-5.0 GHz while consuming 5.7 mW through a 1.8 V supply voltage. Over the 3.1 GHz-5.0 GHz frequency band, the minimum noise figure (NF) is 4.7 dB. Input return loss lower than -12.7 dB in all bandwidth have been achieved.
