In this work,we design a fifth-order chaotic circuit with HP memristors, which consists of a flux-controlled memristor and a charge-controlled memristor. By changing the control parameters, the circuit evolves into different orbits, such as periodic orbits, double-scroll, of single-scroll. In order to ensure the occurrence of chaotic behaviors in the circuit, simulators of the charge-controlled memristor and the flux-controlled memristor are designed with conventional electronic devices, and Pspice simulation is conducted on the resulting circuit. Pspice simulation results verify the correctness of the theorectical analysis.
