Original Abstract

This paper presents two solutions for an amplitude automatic gain control circuit implemented in a simple secondorder quadrature oscillator based on the non-inverting band-pass filtering response and a block with positive feedback with controllable gain or intentional nonlinearity. The results regarding amplitude stability, total harmonic distortion, available tunability range, time required to obtain stable oscillations, etc. are discussed and both AGC solutions are compared. PSpice software was used for verification in simulations.

Keywords
