The multistable memristor entangled nonlinear circuit with a multistable state comprises a first channel, a second channel, a third channel and a fourth channel, wherein simulation of a dimensionless mathematical model is achieved through circuit connection of the four channels, and simulation is achieved through cooperation of a power source V1, a power source V2, a power source V3, a power source V4, a switch K1, a switch K2, a switch K3 and a switch K4; if theinitial value is determined at will, closing the switch K1, the switch K2, the switch K3 and the switch K4 to enable a capacitor C1, a capacitor C2, a capacitor C3 and a capacitor C4 to be charged toreach corresponding voltage values, so as to realize the multi-stable coexistence of the circuit. The memristor entangled nonlinear circuit with a multistable state has the advantages that the circuit structure is simple; the implementation is easy; various state waveforms can be generated; and the output signal is used as a carrier signal to be modulated with a target signal through a related algorithm under the condition of not changing parameters, so that the purposes of secret communication, cracking resistance, image encryption and the like can be achieved.

Description

technical field [0001] The invention belongs to the field of circuits, in particular to a memristive entanglement nonlinear circuit with multi-stable states. Background technique [0002] In 1971, when Professor Cai Shaotang was studying the relationship between voltage, current, magnetic flux and charge, according to the relationship between them, he discovered an undefined and discovered circuit component - memristor, which is used to represent charge relationship with magnetic flux. Since 2008, the HP laboratory successfully prepared a nanoscale memristor for the first time, which has attracted the attention of many researchers. Memristor's unique volt-ampere characteristics and "memory" characteristics make it easy to realize chaos and oscillation in the circuit, so it has aroused widespread interest of researchers in the construction of memristive nonlinear circuits, especially in memristive chaotic circuits and memristive circuits. There is a lot of room for developm...
