<p>because when negative feedback, the output and the input maybe linear, so can not use to compare two signals</p>添加评论

<p>the difference between noninverting and inverting inputs would get reduced and approach to zero due to the negative feedback. the op. and its feedback circuit would act as a linear amplifier.</p>添加评论
