Novel Single-CFOA-based Sinusoidal Oscillator Capable of Absorbing All Parasitic Impedances

Abstract

Although a large number of single current feedback op-amp (CFOA)-based sinusoidal oscillator circuits have been proposed in the literature, to the best knowledge of the authors, no single-CFOA oscillator configuration has been reported earlier which can absorb all the parasitic impedances of the CFOA in the various external passive elements employed. The major intention of this paper is to report such a circuit. The workability of the proposed circuit has been confirmed by experimental results employing an AD844-type CFOA.
