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.

A unified modeling approach for DC-DC converters based on the three-state switching cell

In this paper a new active element namely Dual X current conveyor differential input transconductance amplifier (DXCCDITA) is proposed. The DXCCDITA is utilized in designing eight topologies of lossy and lossless grounded inductor simulators and two topologies of floating inductor simulators. All the designed grounded simulators require only two passive elements and a single active block. The two floating inductor simulators require a single active block and one or three grounded passive elements. In addition, all the designs make use of only grounded capacitors for implementation which is advantageous for fabrication. All the proposed active inductors, except two, did not require any component matching conditions for realization and all the inductor simulators are perfectly tunable. The effect of non-idealities on the proposed grounded simulator structures is also studied. To demonstrate the workability of the inductor simulators they are used in design of second order low pass filter, parallel RLC resonance circuit, third order Butterworth high pass filter, parallel RLC current mode multifunction filter and a voltage mode band pass filter. The DXCCDITA is implemented in 0.35 μm TSMC CMOS technology parameters and tested in Tanner EDA. Sufficient number of simulations are provided to establish the functionality of the active inductor structures.
