摘要

利用Pspice模拟器对mosfet低噪声放大器(LNA)和BJT LNA进行了仿真比较。采用0.5 /spl μ m CMOS MOSIS工艺对MOSFET LNA进行了仿真设计。结果表明，采用低成本、高集成度的CMOS技术可以降低功耗和频率响应，而双极技术的性能要好得多。在工作频率为1.0 GHz的情况下进行比较。

A comparison of CMOS and BJT RF-LNAs

A simulation comparison of MOSFETs low noise amplifier (LNA) versus BJT LNA is proposed using a Pspice simulator. The MOSFET LNA was simulated and designed with a 0.5 /spl mu/m CMOS MOSIS process. It was concluded that the use of low-cost and high integration CMOS technology results in a penalty in the power dissipation and frequency response which are much better in bipolar technology. The comparison is performed at an operating frequency of 1.0 GHz.
