A novel single-capacitor single-operational-amplifier sinusoidaloscillator

By M.T. Abuelma’atti, S.S. Buhalim and H.A. Alzaher

Abstract

The well known operational amplifier based Schmitt-trigger square wave generator is shown to behave as a sinusoidal oscillator at relatively high frequencies. This is attributed to the widely ignored frequency-dependence characteristic of the differential gain of the operational amplifier. Experimental results are in excellent agreement with theoretical prediction
