Distortion in Positive and Negative Feedback Filters

Authors: Bonello, Oscar J.

AES Convention 72 · Paper 1905 · October 1982

Abstract

It is known that the harmonic distortion of an active filter is greater than the distortion of the operational amplifier itself. This paper analyzes positive and negative feedback linear filters; Buttersworth, Chebyshev, Bessel and bandpass filters. The distortion multiplication factor is defined (Kd) and it is plotted versus frequency. Through a computer calculation program, the maximum values of Kd found for several filters configurations, will be given in an useful way for filter designers.
