An Ultra-Wideband CMOS low noise amplifier For 3–5 GHz UWB wireless receivers

An UWB (Ultra Wide Band) low noise amplifier (LNA), which is designed with the HJTC’s 0.18μm CMOS process, is presented in this paper. Simulation results show a gain from 10 to 13.3 dB over a bandwidth range from 3 to 5 GHz. This LNA achieves a noise figure less than 5.5dB and power dissipation less than 12.5mW under a power supply of 1.8V. The input/output return loss is higher than 9/14 dB.
