Accurate unilateral models for the amplifier circuits and their applications

Simple and fast methods of obtaining unilateral models for both single-stage and multi-stage amplifiers are given. They facilitate obtaining the transfer functions of such amplifiers quickly. They also eliminate the need for exact analysis of such circuits and are less error-prone. Applications are provided in analyzing feedback amplifiers to show the versatility, accuracy, and superiority of the methods developed. As a result of the accuracy of the methods presented, the authors use them in various applications to amplifier circuits, such as determining their bandwidth, stability margins, and closed-loop poles, etc
