摘要

介绍了一种用于GSM接收机前端的全cmos宽带低噪声放大器。电路采用不需要任何调谐或修剪的拓扑结构。放大器在0.9 GHz和1 GHz之间提供24 dB的正向增益，而-3dB的频段范围为420 MHz到1.2 GHz。在0.8 GHz ~ 1.1 GHz的整个300mhz频段内，噪声系数小于2.7 dB。在整个测量范围内，反向隔离优于43.5 dB。原型已经在一个0。4 ~ CMOS技术，从2.7伏特电源消耗35兆瓦。

A 2.7 Volt CMOS Broadband Low Noise Amplifier

A full-CMOS broadband low-noise amplifier for application in a GSM receiver front-end is presented. The circuit employs a topology which does not require any tuning or trimming. The amplifier provides a forward gain of 24 dB between 0.9 GHz and 1 GHz, while the -3dB band ranges from 420 MHz to 1.2 GHz. The noise figure is less than 2.7 dB in the whole 300 MHz frequency band between 0.8 GHz and 1.1 GHz. Reverse isolation is better than 43.5 dB over the full measuring range. The prototype has been implemented in a 0 . 4 ~ CMOS technology and consumes 35 mW from a 2.7 Volt supply.
