Abstract

The invention discloses an analog circuit for realizing the characteristics of a memory inductor. The circuit comprises a memory inductor equivalent circuit and a magnetic flux generating circuit; the magnetic flux generating circuit is composed of an integrated operational amplifier U1 and is adopted as the input of the memory inductor equivalent circuit, wherein the integrated operational amplifier U1 is used for realizing a first integrator and a reverse amplifier; the memory inductor equivalent circuit includes an integrated operational amplifier U1 and a multiplier U2, wherein the integrated operational amplifier U1 is used for realizing a second integrator and an adder; the reverse amplifier and the second integrator are connected with the multiplier, so that signal multiplication can be realized, and output acts on the adder, so that final memory inductor current quantity can be obtained. The analog circuit only includes one integrated operational amplifier chip and one multiplier, so that the analog circuit has structural simplicity. The analog circuit of the invention can replace an actual memory inductor when the actual memory inductor cannot be obtained at present and in the further, so that circuit design, experiments and application related to the memory inductor can be realized. The analog circuit is of great practical significance for the characteristic and application research of the memory inductor.

Description

technical field [0001] The invention belongs to the technical field of circuit design, and relates to the realization of an equivalent circuit of a memristor model, in particular to an analog circuit for realizing the characteristics of a memristor. Background technique [0002] As a new type of circuit components with memory characteristics, memristors are nonlinear components after memristors. With the physical realization of memristors, Ventra et al. further expanded the scope of memory components and proposed two new concepts of memory components: memcapacitors and memristors. As a class of basic circuit components with memory properties, memristors, memcapacitors, and memristors have attracted widespread attention for their applications in nonlinear circuits. Because of their memory properties, they can be used in non-volatile memories and artificial neural networks. At present, there are a large number of literature reports on the simulation modeling and circuit real...
