Abstract

This paper introduces the modified single input Op-Amps memristor based oscillator. The oscillator is realized with ideal, LM741 and current feedback (AD844) Op-Amps where memristors replace resistors. The effect of memristor on the oscillation frequency and the oscillation condition that are totally independent is studied. This helped in studying the whole operation regime of the memristor. The effect of initial conditions on the circuit behavior is discussed. The dynamic poles of the oscillator after resistors replacement are illustrated. Sustained oscillation is obtained and simulated results are nearly matched to the calculated results.
