In this paper a CMOS dual-wideband low-noise amplifier (LNA) is designed for ultra-wideband (UWB) wireless receiver radio system. The design consists of a wideband input impedance matching network, two stage cascode amplifiers with shunt-peaked load, two 2(nd)-order notch fitters and an output buffer for measurement purpose. It is simulated in TSMC 0.18um standard CMOS process. The LNA gives 13.1dB maximum power gain between 3.0GHz-4.9GHz and 15.5dB maximum power gain between 6.2GHz-10.2GHz while consuming 21.9mW through a 1.8V supply. Over the 3.1GHz-4.9GHz frequency band and the 6.2GHz-10.2GHz,a minimum noise figure is 2.5dB and 2.8dB. Input return loss lower than 6.4dB in all bandwidth have been achieved.

A multi-stage low-noise amplifier (LNA) with LC-tank load to extend the bandwidth is designed for ultra-wideband (UWB) wireless receiver. The design consists of three LC-tank cascode amplifier and one output buffer and is implemented in 0.18um RF CMOS process. The LNA gives 14.5dB gain and 7.2GHz 3dB bandwidth (3.1 - 10.3GHz) while consuming 22.8mW through a 1.5V supply. Over the 3.1GHz - 10.3GHz frequency band, a minimum noise figure of 2.6dB and input return loss lower than -8.8dB have been achieved.
