An Equivalent Circuit of a Fractional Memcapacitor

Abstract

The invention relates to an equivalent circuit of a fractional memory capacitor. According to the technical scheme, an input current ia(t) of the equivalent circuit of the fractional memory capacitoris processed through a first resistor (25), a second resistor (26), a first capacitor (22), a first current transmitter (1) and a first amplification module (2) to obtain a voltage value V02 of a charge signal of the equivalent circuit; VE is amplified through a second amplification module (4) and is subjected to phase shift by a voltage-controlled phase shifter (19); an introduced control signalalpha is calculated by a first calculation module (7), a second calculation module (15) and a third calculation module (17) to obtain corresponding voltage value K1, voltage value K2 and voltage valueK3; and a circuit composed of the first current transmitter (1), a second current transmitter (18), a third current transmitter (20) and the first capacitor (22) enables the input current ia(t) of the equivalent circuit of the fractional memory capacitor to be equal to an output current ib(t). The equivalent circuit can be accurately simulate the electrical property of the fractional memory capacitor, and has the characteristics of convenient order adjustment, easy control and high precision.

Description

technical field [0001] The invention belongs to the technical field of equivalent circuits of memcapacitors. In particular, it relates to an equivalent circuit of a fractional memcapacitor. Background technique [0002] In 2009, Ventra, Professor Cai Shaotang and others expanded the concept of memory elements on the basis of memristors (Ventra M D, Pershin Y V, Chua L O. Circuit Elements With Memory: Memristors, Memcapacitors, and Meminductors[J].Proceedings of the IEEE,2009,97(10):1715-1716), and after giving the relevant definitions of memcapacitors and memristors, the characteristics of memory components have attracted the attention of more researchers. [0003] According to the conversion relationship between memristors and memcapacitors, Pershin et al. used existing circuit components to design circuits that satisfy this conversion relationship, and converted memristors into memcapacitors (Pershin Y V, Ventra M D. Memristive circuits simulate memcapacitors and memindu...
