Realization of Solid Fractional Order Capacitor Using Common Materials

2021 IEEE Second International Conference on Control, Measurement and Instrumentation (CMI), 2021
Fractional order element is the most basic components for realization of fractional order systems. A solid fractional order capacitor (FOC) is observed to be capable of replacing bulky ladder RC circuits without altering the system’s behaviour. Instead of an ordinary, conventional and high cost semi-solid FOC, the idea is to design an economically ...

Two Capacitor Problem with a LTI Capacitor and a Capacitor Modelled Using Conformal Fractional Order Derivative

European Journal of Engineering and Applied Sciences, 2021
Fractional order circuit elements have been started to model different types of circuit elements, circuits and systems in the last decades. There are different types of fractional derivatives. Recently, a new simple fractional derivative method called“conformable fractional derivative” has been brought out.

Quantification of memory in fractional-order capacitors

Journal of Physics D: Applied Physics, 2019
In this study we quantify and interpret the inherent memory in fractional-order capacitors when subjected to constant current charging/discharging waveforms. This is done via a finite difference approximation of the fractional order rate equation relating current to voltage in these devices.

Capacitorless fractional-order filters and capacitor/inductor emulators

2017 Panhellenic Conference on Electronics and Telecommunications (PACET), 2017
Fractional-order filters as well as capacitor and inductor emulators, implemented using current-mirrors as active elements are presented in this work. Due to the utilization of the internal gate-source capacitance of MOS transistors or of the appropriately configured MOS transistors as capacitors, there is an absence of passive capacitors in the ...

Simple MOS Transistor-Based Realization of Fractional-Order Capacitors

2019 IEEE International Symposium on Circuits and Systems (ISCAS), 2019
A new second-order MOS transistor based circuit block approximating the behavior of a fractional-order capacitor is proposed. The circuit is modular and therefore the order of the approximation can be increased by more stages of the same circuit in cascade or in parallel.

Study of the parameters of a fractional order capacitor

2015 Annual IEEE India Conference (INDICON), 2015
A fractional order capacitor of desired specification can be realised by dipping a capacitive type probe, coated with a porous film of polymer of particular thickness, into a polarizable medium [1]. The aim of this work is to identify all the parameters responsible for the impedance of the fractional order capacitor and then to find a relationship ...

Implementation of improved fractional order capacitor approximations in analog circuits

2016 1st India International Conference on Information Processing (IICIP), 2016
The paper aims at various techniques to approximate fractional capacitor using passive elements. The fractional capacitors have been used to implement an astable multivibrator, sinusoidal oscillator, function generator and filters. PSPICE simulation results have been shown for the circuits both with and without using the fractional capacitors.
