摘要：

A simple modification is proposed for a popular common-mode feedback circuit used in operational amplifiers, such that it can be used in an operational transconductance amplifier (OTA) without leading to significant DC offset caused by the unavoidable tuning of the OTA. Simulation results show that the improved circuit has nearly zero DC offset for the whole tuning range.
