摘要
针对放大电路的反馈类型多,判断过程复杂的问题,提出对于基本放大电路和集成运放电路构成的反馈电路,需要一种简捷、快速的判断方法来解决这一问题。通过多年的理论研究和实践教学,分析各种电路图,研究相关理论,总结了一套运用20字或7字口诀法进行快速、有效、准确判断放大电路各种反馈类型的方法。
Facing the problems of many feedback types of amplifier circuit, and their complicated judging process, a teedback clrcuit composed by the basic amplifying circuit and integrated operational amplifier circuit was presented in this paper, which needed a simple and quick judgment method to solve.During years of theoretical research and practice teaching, by analyzing all kinds of circuit diagrams and the related theories, a set of 20 words or 7-word-pithy formula was summarized to judge various types of feedback of amplifier circuit rapidly, effectively and accurately.
