5 Feedback, Frequency Response, and Amplifier Stability

5.1 INTRODUCTION

This chapter describes the details of how feedback changes an open-loop amplifier’s frequency response and examines how negative voltage feedback (NVF) and positive voltage feedback (PVF) can lead to amplifier instability. Practical use can be made of instability; we can design tunable sinusoidal oscillators using the same analytical techniques used in the design of linear feedback amplifiers.

Over the years, there have been many analytical techniques used to analyze and design feedback systems. In the author’s opinion, the root locus technique is one of the more useful techniques. ...
