摘要：

Common-mode rejection ratio (CMRR) analysis in analytical form requires a careful treatment on the differential component in an operational amplifier (opamp) circuit. If not carefully modeled, inaccurate numerical result will be generated. In this work we improve an existing gain perturbation method by introducing a systematic procedure and show the improvement via an example.
