摘要

介绍了一种用于视频应用的14阶CMOS跨导- c (Gm-C)带通滤波器。通过使用高度线性的Gm-C积分器，该滤波器在700 kHz噪声带宽下实现75 dB动态范围。对于4 Vpp输入信号，测量的IM3 @ 600 kHz为-61 dB。片上自动频率调谐提供超过300%的滤波器中心频率范围，频率精度为1%。0.7 /spl mu/m CMOS滤波器测量4.8 mm/sup /，单个5v电源消耗70 mW。

A highly linear CMOS Gm-C bandpass filter for video applications

A 14th order CMOS transconductance-C (Gm-C) bandpass filter for video applications is described. By using highly linear Gm-C integrators, the filter achieves 75 dB dynamic range over 700 kHz noise bandwidth. The measured IM3 @ 600 kHz is -61 dB for a 4 Vpp input signal. On-chip automatic frequency tuning provides more than 300% center frequency range of the filter with 1% frequency accuracy. The 0.7 /spl mu/m CMOS filter measures 4.8 mm/sup 2/ and consumes 70 mW from a single 5 V power supply.
