摘要

A novel high CMRR current output stage (COS) with QFG is presented in this paper. A novel common mode feedback (CMFB) is used to reject the common mode signal in order to achieve high CMRR. The common mode signal is omitted by the technique of adding the main signal and its opposite polarity one. 112 dB of CMRR is obtained in 0.35 urn CMOS technology with ±0.75 v supply voltage and only 182 uw power dissipation which shows good improvement compared to the other work in the literature.
