最近文献[1]提出一个测量运算放大器的共模抑制比的新方法,称为“失调电压法”.它与某些变电源测量方法一样,存在着一定的原理误差.
Recently, a new method to measure the common-mode rejection ratio of operational amplifiers was proposed in the literature [1], which is called “offset voltage method.” It has the same principle error as some variable-power measurement methods.
