运算放大电路教学方法研究

运算放大电路是模拟电子技术的核心电路之一,经典教材中分析该电路功能特性时采用线性电路多种分析方法,在教学中发现学生难以接受。该文明确提出利用元件约束VCR和结构约束KCL结合理想运放虚短虚断特点分析电路,经过课堂实践,发现该分析方法有助于学生对运算放大电路的理解,提升了学生对该知识点的掌握,有助于模拟电子技术课程的学习。

Operational amplifier circuit is one of the core circuits of analog electronic technology.It is difficult for students to understand when the traditional linear circuit analysis methods are used to analyze the functional characteristics of operational amplifier circuit.The method of analyzing the operational amplifier circuit by using the component constrained VCR and structure constrained KCL combined with virtual short and virtual break characteristics is proposed in this work.The results of classroom practice show that the new method is helpful for understanding the operational amplifier circuit,and the learning of analog electronic technology course.
