本文对《电气电子教学学报》第 2 0卷第 3期中的“对负反馈讲法问题的探讨”一文中的某些不妥之处提出异议 ,阐明了对于不同的教育对象 ,负反馈的讲法宜采用不同方法 ,强调结合集成运算放大器的线性应用电路讲解负反馈 ,同时指出了集成运算放大器的“虚短路”概念与深度负反馈的本质关系。
This paper disagrees on some of the defects in the article “Discussion on the Negative Feedback Talks” in Vol. 20, No. 3 of the “Journal of Electrical and Electronic Teaching”, clarifies that for different educational objects, the negative feedback should be appropriate Different methods are adopted to emphasize the linear feedback circuit of the integrated operational amplifier. At the same time, the essential relationship between the concept of “imaginary short circuit” and the deep negative feedback of the integrated operational amplifier is pointed out.
