Problems solved by technology

[0003]Currently, the reported memristor simulation models include PSPICE simulation model and hardware equivalent circuit of simulated memristor. On the one hand, the principles of these two types of memristor models are complex , difficult to realize in practice; on the other hand, it is difficult for these two types of memristors to accurately simulate the characteristics of actual memristors

Description

technical field [0001] The invention belongs to the technical field of circuit design, and in particular relates to an equivalent analog circuit of a multi-stable magnetron memristor. Background technique [0002] Memristor is the fourth basic circuit element after resistance, capacitance and inductance. It describes the relationship between magnetic flux and charge, and has characteristics that cannot be copied by any combination of the other three basic circuit elements. It is a kind of Non-linear resistance with memory function. In 1971, Chua theoretically predicted the existence of memristor elements according to the completeness theorem of basic circuit variable combinations. It was not until 2008 that Hewlett-Packard Labs made a physical TiO2 memristor for the first time. Memristors can remember the amount of charge flowing through it, which makes it a natural non-volatile memory. The emergence of memristors has made integrated circuit components small and portable.
