摘要
研究分析了典型放大器共模抑制比的计算模型,根据影响共模抑制比的因素和一般计算模型的缺点,在基于非理想运放的基础上,提出一种共模抑制比的计算模型。经验证,提出的计算模型和方法能够改善高共模抑制比,并且是有效合理的。
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.
