Abstract

A simple expression is derived for the common-mode rejection ratio (CMRR) of the differential operational amplifier with shunt common-mode (CM) feedback. The CMRR is exclusively expressed in terms of a fractional unbalance of the bridge circuit composed of an input resistor pair and a shunt CM feedback resistor pair.
