Novel Feedback Topology Obviates the Need for High Loop Gain

Authors: Didden, Johannes M.

AES Convention 103 · Paper 4597 · September 1997

Abstract

A novel feedback topology is presented, differing from 'classical' feedback by an additional feedback term, inversely proportioned to open-loop transfer function. The result is the elimination of the open-loop transfer function from the closed-loop equation, without requiring high loop gain. An example circuit, implemented with simple means, is discussed, showing a distortion reduction of several orders of magnitude.
