Detailing the fundamental properties of feedback, this book goes on to illustrate techniques of analysis for greater insight into feedback amplifiers and design strategies to optimise their performance. The book has two main purposes: 1) a tutorial purpose since its aim is first to introduce and then to bring the reader to in-depth analysis and design of feedback circuits; 2) to present original material on the topic of feedback circuits. In particular, a new comprehensive approach for the frequency compensation of two-stage and three-stage amplifiers is adopted, and new results are reported for harmonic distortion in the frequency domain.
