Systematic biasing of negative feedback amplifiers

Abstract

A biasing method is described, intended to make automated biasing of at least some classes of analog circuits straightforward. It has been tested for linear amplifiers, though it is not restricted to that class. A systematic way to introduce bias sources in a circuit is discussed. Also methods for reducing the number of bias sources and bias feedback loops are given. Application of the method has shown that at least for the class of amplifiers the theory is well suited for automation.
