In this paper, a new memristor model is proposed and the corresponding emulator is presented to explore its electrical characteristics. A memristive chaotic circuit is designed based on this memristor and a capacitor, which has a conservative nature. The dynamic properties of the system, including high sensitivity to initial values and parameters, coexisting orbits, and transient phenomena, are obtained and investigated by Lyapunov exponents and phase volumes. The chaotic characteristics of the system are confirmed by circuit simulations and experimental devices, which illustrate the validity of the theoretical analyses. Furthermore, a random sequence generator is developed to explore the potential application of the circuit.
本文提出了一种新的忆阻器模型，并给出了相应的模拟器以探究其电学特性。基于该忆阻器和一个具有保守性质的电容器设计了一个忆阻混沌电路。通过李雅普诺夫指数和相体积获得并研究了系统的动态特性，包括对初始值和参数的高敏感性、共存轨道以及瞬态现象。通过电路仿真和实验装置证实了系统的混沌特性，这说明了理论分析的有效性。此外，还开发了一个随机序列发生器以探索该电路的潜在应用。
