A memristor-based Wien-bridge sinusoidal/chaotic oscillator

Abstract

This paper presents the experimental results obtained from a memristor-based Wien-bridge oscillator implemented using a new memristor emulator. The memristor emulator can be implemented using off-the-shelf components. The experimental results show that nonlinear chaotic as well as linear oscillations can be obtained from the same circuit by careful adjustment of the value of a single resistor. The proposed circuit can be easily presented in an undergraduate laboratory course to demonstrate the use of memristors in generating chaotic oscillators.
