摘要

介绍了一种采用HJTC 0.18 μ m CMOS工艺设计的超宽带低噪声放大器(LNA)。仿真结果表明，在3 ~ 5 GHz的带宽范围内，增益为10 ~ 13.3 dB。该LNA在1.8 V电源下噪声小于5.5 dB，功耗小于12.5 mW。输入/输出回波损耗大于9/ 14db。

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 0.18 mum 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 5.5 dB and power dissipation less than 12.5 mW under a power supply of 1.8 V. The input/output return loss is higher than 9/14 dB.
