“…The dynamic properties of some memristive devices are usually more attractive. For instance, the resistive switching dynamics of nonvolatile memristive devices are used in relaxation oscillators [9] or to enhance the dynamic behavior in chaotic circuits [10], [11], [12]. Furthermore, the metal-insulator transition in Mott memristors paved the way towards extremely compact oscillators exhibiting self-sustained periodic oscillations [13], [14], [15], and even chaotic patterns [16].…”

“…Therefore, the opportunity to establish the foundations for the implementation of Chua's circuit with real memristive devices is yet to come. It is worth mentioning that while [11], [12] implement different modified versions of Chua's circuit by introducing real memristive devices, both of them do not replace the nonlinearity required for generating chaos. Therefore, the memristive device neither plays an exclusive role in chaos generation nor adds control to the system's dynamic response.…”

Nonvolatile memristive devices display nonlinear characteristics suitable for implementing circuits exhibiting oscillations or more complex dynamic behaviors, including chaos. However, the results presented in related works are mostly limited to simulations and employing ideal memristor models whose resistance is governed by a charge-flux relation that is not connected to real devices, thus hindering the realization of such nonlinear oscillators. In this work, we present the framework for the physical implementation of a tunable memristor Chua's circuit, which is based on a nonvolatile memristive device that provides the nonlinear conductance required by the circuit and the possibility to tune it for the purpose of selecting among different oscillation patterns. We first establish design guidelines to guarantee complex oscillations in the tunable memristor Chua's circuit. Further, we physically implement the circuit after characterizing and modeling the tunable current-voltage characteristic of a real device. Our circuit successfully generates different oscillation patterns just by programming the nonvolatile memristive device to different states. The devised design guidelines and device modeling were used to extend the experimental work and draw further requirements for device properties for a successful circuit implementation.

This paper discusses the complex dynamic behavior of a novel chaotic system, which was firstly established by introducing a memristor into a similar Chen’s system. Then by choosing a as the key parameter, we analyze the stability of memristor system based on eigenvalue theory. It is also found that when a cross some critical values, the system can exhibit Neimark–Sacker bifurcation and chaos behaviors. Some numerical simulations including phase diagrams and maximum Lyapunov exponent graph of the memristor-based systems are presented to verify the existence of chaos attractors. Finally, to make the results of this paper useful in the actual situation, such as the design of chaos security algorithm, analog electronic circuit of memristor chaotic system is designed.
