Design and simulation of a memristor chaotic circuit based on current feedback op amp

Abstract

In this work, we propose a novel memristor chaotic circuit, which combines current feedback op amp with four basic electronic components, such as capacitance, inductance, resistance and memristor. The dynamic properties of the new circuit are demonstrated, such as system dissipation, equilibrium stability, phase portrait, Lyapunov exponent spectrum, and parameter influence. Numerical simulation results show that the circuit produces a kind of special chaotic attractor and exhibits complicated chaotic behaviour with the evolution of the system parameters. In order to confirm the correctness of the system, a realizing circuit is designed, Pspice simulation results verify the correctness of theoretical analysis.

Simulation and experimental implementations of memcapacitor based multi-stable chaotic oscillator and its dynamical analysis

“…The last decade has seen a growing trend towards development of many other memristor models [3][4][5][6]. Many chaotic oscillators with memristive elements are discussed widely such as the flux controlled memductance models [7][8][9], anti-parallel two memristors [10], a current feedback operational amplifier based memristor systems [11] and Digital Signal Processors implementing memristor [12]. A new two memristors hyper chaotic system tested for image encryption is investigated [13] showing that the memristor based chaotic generators are more complex and useful in cryptography.…”
