摘要

本文介绍了一种低中频拓扑的GSM接收机多相滤波器的设计，采用单片机集成性能的有源rc电路方案。基于台积电0.18¿m CMOS工艺，Spectre仿真结果表明，该滤波器以110 kHz为中心，带宽为200 kHz。它的电压增益约为30 dB，图像抑制比约为38 dB。在3v电源下，功耗为4.2 mW。

Design of an active polyphase filter in GSM receiver with low-IF topologies

This paper describes the design of a polyphase filter in GSM receiver with low-IF topologies, using the circuit scheme of active-RC with the performance of single chip integrated. Based on TSMC 0.18 ¿m CMOS process, the Spectre simulation results indicate that the filter is centered at 110 kHz with 200 kHz of bandwidth. It has a voltage gain of about 30 dB, an image rejection ratio of about 38 dB. The power consumption is 4.2 mW under a 3 V power supply.
