Quantification of memory in fractional-order capacitors
Journal of Physics D: Applied Physics, 2019Abstract 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 ...

Experimental verification of on‐chip CMOS fractional‐order capacitor emulators
Electronics Letters, 2016 The experimental results from a fabricated integrated circuit of fractional‐order capacitor emulators are reported. The chip contains emulators of capacitors of orders 0.3, 0.4, 0.5, 0.6 and 0.7 with nano‐Farad pseudo‐capacitances that can be adjusted through a bias current.

Analysis of a rectifier circuit realized with a fractional-order capacitor
2016 28th International Conference on Microelectronics (ICM), 2016An analysis of a traditional rectifier circuit when a fractional-order capacitor with order 0 < α < 1 replaces the integer-order smoothing capacitor (α = 1) is presented. Exploring the change in discharging behaviour that results from this replacement and the impacts on ripple voltage, nominal DC voltage, current, and power expressions used to describe

Realization of Solid Fractional Order Capacitor Using Common Materials
2021 IEEE Second International Conference on Control, Measurement and Instrumentation (CMI), 2021Fractional 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 ...

A dualband impedance transformer realized by fractional-order inductor and capacitor
2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2016A novel dualband impedance transformer based on fractional-order inductor and capacitor is proposed in this paper. This transformer is designed to transfer the arbitrary frequency-dependent complex impedances sources to loads at two irrelevant frequencies with one fractional-order inductor and two fractional-order capacitors.

Simple MOS Transistor-Based Realization of Fractional-Order Capacitors
2019 IEEE International Symposium on Circuits and Systems (ISCAS), 2019A 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.

In this paper, based on the concept of restricted difference basis RDB for a natural number, the general structures of the pseudo state-space realisations of some classes of commensurate fractional-order transfer functions are obtained. It is shown that the number of needed fractional-order capacitors for implementing a transfer function belonging to ...

IET Power Electronics, 2016 Being one of the most used passive components in power electronics, electrolytic capacitors have the shortest life span due to their wear‐out failure which is mainly caused by vaporisation and deterioration of capacitor electrolyte. Knowing these two phenomena increase equivalent series resistance (ESR) of the capacitor, tracking ESR value over the ...
