VDTA and DO-CCII based incremental/decremental floating memductance/meminductance simulator: A novel realization

Abstract

The meminductor element is useful just like the memristor element due to the similar kind of hysteresis property found in its transient characteristics. This study presents a floating memelement emulator to realize the dual memelement function (memristor and meminductor) using a VDTA (Voltage Differencing Transconductance Amplifier) and a DO-CCII (Dual Output Second Generation Current Conveyor) based compact circuit configuration. The developed emulator architecture requires only three passive elements (all in the grounded state) with just two active elements to realize the floating meminductor and memristor suitable for both incremental as well as decremental modes of operation. The tuning of the proposed circuit to provide desired memelement behavior realization (memristor or meminductor) can be obtained by selecting an employed grounded impedance as a capacitor and resistor respectively. No use of any floating passive element and external memristor emulator is a remarkable design feature along with the feature of tunability found in the proposed emulator circuit enriching the superiority of its design. The circuit analysis also shows that the selection of the grounded impedance as an inductor can also lead to the realization of a non-linear capacitor, which is the dual of a memcapacitor element. The workability of the presented emulator circuit is validated through the simulations generated for the 0.18μm CMOS technology in the PSPICE environment. The application examples of both the realized floating elements have been presented and verified through the presented simulation results. Also, the reported memelement emulator has been implemented and verified by using commercially available ICs; AD844 and LM13700.
