摘要
本文提出一条建立放大器单向化模型的新途径,由该单向化模型可以非常容易地获得放大器的传递函数。与传统的确定放大器传递函数的密勒效应近似法和时间常数法相比,本文的方法不仅十分简单,而且精确度也较高。
A new approach to get unilateral models for amplifiers is given. The transfer functions of such amplifiers are easily obtained by using the models. Compared with the traditional methods for determing transfer functions of amplifiers, such as the approximate method based on the Miller effect and the time constant method, the method presented in this paper is not only simple but also highly accurate.
