A floating memristor emulator circuit using operational transconductance amplifiers

This paper presents a floating memristor emulator circuit using operational transconductance amplifiers (OTAs). The OTAs are used to realize electronically tunable second-generation current conveyors (ECCIIs). The behavior of a titanium dioxide (T_iO₂) memristor model of Hewlett-Packard laboratories has been imitated in the form of emulator circuit using ECCIIs. The hardware of proposed memristor emulator can be built using low cost devices that found in the market. The memristor emulator can be used as both the simulations and experiments which is valuable in a teaching aid and a real circuit application. Simulation and experimental results are also given to confirm the workability of the proposed circuit.
