Emulation of versatile tunable universal mem-elements design and its application

Abstract

This study proposes the use of an active building block Operational Transconductance Amplifier (OTA), three transconductor elements, and a few passive components to design an electronically tunable universal mem-elements emulator circuit that includes memristor (MR), memcapacitor (MC), and meminductor (MI). Mem element’s physical realization is still an open challenge that drives the creation of new designs. The universal circuit requires one floating resistor and two grounded capacitors as passive components. The topology of mem-elements has been implemented using a switch without altering the circuit structure. The workability of memristor and meminductor don’t require any resistor while memcapacitor requires the use of one resistor. The presented design establishes a simple mathematical relationship and verifies Memristive system fingerprint traits such as pinched hysteresis loop (PHL). The functionality of the suggested universal mem-elements architecture is confirmed by the PSpice simulation results for implementing all three characteristics in the 0.18 μm CMOS technology node. Implementation using commercial ICs further validates the circuit’s performance beyond its CMOS-based architecture. The functioning of the suggested architecture is demonstrated by application various examples. The MR, MC, and MI emulation circuits have been shown to consume 7.4 mW, 11.2 mW, and 10.4 mW of power, respectively
