Abstract
In this note we discuss the reverse gain of feedback amplifiers; a parameter often neglected in the feedback analysis presented in most textbooks on electronics. The discussion presented here shows how this reverse gain can have a significant impact on the feedback circuit input and output impedances, even when such a gain is negligible and the circuit is considered as ‘unilateral’.
