Electronically Tunable Circuit Realization of Multimemelement Function Simulator and Its Application to Chaos Generation

Abstract

The paper presents a very compact dual memelement function simulator using only one active building block (ABB) namely modified Voltage Differencing Current Conveyor (mVDCC), two MOSFETs, and two grounded passive elements. The proposed emulator can realize the function of memristor, meminductor, and memcapacitor-dual, which can be achieved via the proper selection of only one grounded passive element as R, L, and C. The proposed multimemelement emulator (MME) is fully electronically tunable and exhibits nonvolatile storage property. Also, the emulator can exhibit memristor response up to MHz range of frequency. The PSPICE-generated simulation results verify the working of the given floating MME for the realization of all three elements using 0.18 [Formula: see text]m CMOS technology node. The presented CMOS layout shows that the proposed emulator implementation occupies an area of [Formula: see text]. Along with the CMOS-based structure, the presented MME is verified through commercial ICs-based implementation. The given application example of the chaotic circuit also proves the working of the presented MME.
