摘要

本文提出了一种可调谐50 kHz-2 MHz 3/sup /阶低通巴特沃斯Gm-C滤波器，用于零中频蜂窝多标准接收机(包括GSM/DCS/PCS和W-CDMA)的基带模块，该滤波器采用0.25 /spl μ m, 2.5 V SiGe BiCMOS工艺设计和制造。测量显示出良好的带内线性度(高达+18 dBVp)，大调谐范围(>30:1)，中等噪声和功耗(每通道1 mW至4 mW)，硅面积仅为0.5 mm/sup 2/ (I&Q通道)。

A multi-mode continuously-tunable lowpass filter for zero-IF mobile applications

This paper presents a tunable 50 kHz-2 MHz 3/sup rd/-order lowpass Butterworth Gm-C filter for use in a baseband module of a zero-IF cellular multistandard receiver, including GSM/DCS/PCS and W-CDMA, designed and fabricated in a 0.25 /spl mu/m, 2.5 V SiGe BiCMOS process. Measurements exhibit good inband linearity (up to +18 dBVp), large tuning range (>30:1), moderate noise and power consumption (1 mW to 4 mW per channel) for a silicon area of only 0.5 mm/sup 2/ (I&Q channels).
