摘要：

A novel CMOS differential input stage for transconductance amplifiers is presented that combines a low noise excess factor (NEF), low input capacitance, and high CMRR with a very good linearity. Measured distortion is only 0.2% for a 1-V rms input signal and only 1% for a 2-V rms input signal, on a test circuit implemented in a standard 3- p.m CMOS process, using ± 5-V supplies. This results in over 85 dB of dynamic range. Applications include high-performance continuous-time filters and linear amplifiers. 0018-9200/90/0400-0497$01.00 © 1990 IEEE
