New Electronically/Resistively Tunable Floating Emulators to Realize Memristor and Inverse Memristor

This article presents the architectures of two emulator circuits, which realize the behaviour of a floating memristor and inverse memristor respectively. Both the presented emulator circuits are based on modified Voltage Differencing Current Conveyor (MVDCC) and grounded passive elements only. The feature of Electronic/Resistance tunability is found in both the emulator circuits. Furthermore, no employment of any external multiplier circuitry can be viewed as an important advantage of the proposed emulators. Also, the utility of the inverse memristor has also been discussed in theoretical discussions. The simulations have been performed to verify the working of all the presented emulator circuits, under PSPICE environment. Moreover, these MVDCC based emulators are also designed using commercially available ICs, LM13700 and AD844.
