High-CMRR Current Amplifier Architecture and Its CMOS Implementation


A novel current operational amplifier, in which the traditionally adopted input current follower is replaced by an input stage that exhibits current gain and single-input-to-differential-output conversion, is presented. Due to this, increased values of both dc gain and common-mode rejection ratio (CMRR) are obtained in the overall amplifier. A CMOS… (More)
