Simple charge controlled floating memcapacitor emulator using DXCCDITA

This research article introduces generalized design procedure for incremental/decremental memcapacitor using analog active device that brings a charge controlled floating memcapacitor emulator. The demonstration of generalized model using Dual X current conveyor differential input transconductance amplifier (DXCCDITA) as an analog active device comes with grounded capacitor and single resistor. The important features of proposed memcapacitor emulator in comparison with other emulators are the absence of mutator and multiplier circuits that causes less design complexity, CMOS compatible circuits, high frequency operation and few more. The switching operation incorporated in proposed memcapacitor model provides incremental and decremental mode of operation to control the state of memcapacitor for real time application. The CMOS implementation of DXCCDITA uses 0.18 µm CMOS technology parameter for the design verification. The performance of the memcapacitor is verified using PSPICE simulation and the observation validates the synchronization of theoretical perspective. An adaptive learning circuit is examined as an application with the proposed memcapacitor model that validates the usage of proposed model.
