SELF-CORRECTING AC AMPLIFIER WITH INDUCTIVE DIVIDER

Balázs Fock, István Zoltán

Abstract

In this paper a self-correcting method is presented to reduce the error of an inverting amplifier below 20 ppm in 0-3 kHz frequency range. The method is based on a two step approch. In the first step the phase error of the amplifier is corrected, and then the methode is extended to the amplitude error reduction.
