Designing Amplifiers for Stability Slides and Transcript

Abstract: Most amplifier designers spend at least as much or more effort assuring stability under all operating conditions with proper frequency compensation than on other amplifier features. This tutorial will revisit the basics of frequency compensation such as Miller, parallel, nested-Miller and feed-forward compensation and compare them in terms of power efficiency and load-drive capabilities. We will look into the loading effects of subsequent stages, common design traps and round up with a case study of recently published amplifiers.
