This paper analyzes the typical amplifier CMRR ratio calculation model.According to the factors affecting the common-mode rejection ratio and the disadvantage of general computational models,a common-mode rejection ratio computational model is proposed based on the non-ideal op amp.Analysis shows that the proposed method can improve the calculation models and high common-mode rejection ratio,and is effective and reasonable.
