Anticausal analysis of feedback amplifiers
Abstract
This paper discloses a technique for the direct analysis of linear active circuits, avoiding the solution of simultaneous equations. This is done by representing the circuit in such a way that the signal variables are determined sequentially: we only allow a signal variable to depend upon previously determined signal variables. Such a circuit is representable by a cascade signal flow graph, a graph containing no feedback loops. This simplification in linear amplifier analysis allows us to trace a clear path from rough design approximations to exact computer analysis.
