Abstract

This paper presents grounded and floating memristor emulators based on current differencing transconductance amplifier. These emulators are realized using current differencing transconductance amplifier, operational transconductance amplifier and a grounded capacitor. Incremental to decremental memristor emulators and vice versa are easily obtained by modifying the circuit slightly. These memristor emulators are very simple in design over other complex realizations reported in the literature. The pinched hysteresis curves have been obtained without using analog multiplier for a wide range of frequency that varies from 600 kHz to 2 MHz. The property of retention has been verified for proposed design of memristor emulators after applying voltage pulse of amplitude 100 mV and frequency 1 MHz. Non-ideal analysis including the effects of parasitic impedances on the behaviour of proposed memristor emulators has also been presented. The proposed designs of memristor emulators have been simulated by Mentor Graphics Eldo simulation tool with TSMC 0.18 µm, level 53, CMOS technology parameters. The performance of proposed memristor emulator is verified by embedding it in the realization of current- mode analog filter.
