Brief Tutorial on HP Memristor-based Chua's Chaotic Oscillator

Abstract

This paper analyzes an innovative chaotic circuit based on Chua's oscillator. It combines traditional realization of a non-linear resistor in Chua's chaotic oscillator with a promising memristive circuitry. This mixed implementation connects old research works that were focused on diodes with relatively new research papers that are, now, concentrated on memristors. As a result, a more reliable chaotic circuit with an HP memristor is obtained that could be used as a source of randomness. Dynamic behavior of the circuit is studied by obtaining FFT analysis, different chaotic attractors and Lyapunov exponent spectrum. The results show that the addition of a memristor enhances the chaotic behavior of the circuit while reducing the power consumption by 1.95%.
