Abstract
In this paper a high gain, low power, low-noise amplifier (LNA) is designed for ultra-wideband (UWB) system. The design consists of a wideband input impedance matching network, one stage cascode amplifier with capacitor-coupling resonated load and it is fabricated in UMC 0.18um standard RF CMOS process. The LNA gives 10.3dB gain and 1.8GHz 3dB bandwidth (3.1 – 4.9GHz) while consuming only 2.39mW through a 1.0V supply. Over the 3.1 – 4.9GHz frequency band, a minimum noise figure of 4.5dB and input return loss lower than −5.7dB have been achieved.
