Fractional Order Capacitor in First-Order and Second-Order Filter

Micro and Nanosystems, 2020
Background: Fractional order Butterworth and Chebyshev (low-pass filter circuits, highpass filter circuits and band-pass filters circuits) types of first and second order filter circuits have been simulated and their transfer function are derived.

Experimental verification of filters using fractional-order capacitor and inductor emulators

2016 39th International Conference on Telecommunications and Signal Processing (TSP), 2016
Fractional-order filter design examples, realized through the substitution of fractional-order capacitors and inductors by appropriate active emulators, are presented in this paper. The implementation of emulators has been achieved using Current Feedback Operational Amplifiers (CFOAs) as active element.

High-Power Fractional-Order Capacitor With $1 2$ Based on Power Converter

IEEE Transactions on Industrial Electronics, 2018
A fractional-order capacitor (FOC) plays a vital role in fractional-order circuits. However, the FOC with order $1 based on existing manufacturing schemes can be only operated in milliwatt power level. Thus, the applications of an FOC in power conversion are limited.

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 ...

Three Fractional-Order-Capacitors-Based Oscillators with Controllable Phase and Frequency

Journal of Circuits, Systems and Computers, 2017
This paper presents a generalization of six well-known quadrature third-order oscillators into the fractional-order domain. The generalization process involves replacement of three integer-order capacitors with fractional-order ones. The employment of fractional-order capacitors allows a complete tunability of oscillator frequency and phase.

Realizations of simple fractional-order capacitor emulators with electronically-tunable capacitance

Integration, 2019
Abstract A novel resistorless topology for implementing fractional-order capacitor emulators, based on the employment of Operational Transconductance Amplifiers (OTAs) as active elements, is presented in this paper. The benefits of this topology are its simplicity in terms of component count, compared to other existing topologies in the literature ...

Determination of a physically correct fractional‐order model for electrolytic computer‐grade capacitors

Mathematical Methods in the Applied Sciences, 2020
Electrolytic computer‐grade capacitors (ECGCs) are vastly implemented in energy storage systems. However, their models are not accurate and simple as other kinds of capacitors. For example, ECGCs and supercapacitors share many characteristics but have some differences because of their physicochemical properties, so it is wrong to assume their ...

On the behavior of distributed networks of fractional-order capacitors

Journal of Physics D: Applied Physics
Abstract Fractional calculus has seen tremendous applications in the past couple of decades particularly in the electrochemistry field for the modeling of anomalous dynamics at electrode/electrolyte interfaces. At the core of this is the fractional-order capacitor (also known as the constant phase element (CPE ...

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.

Design, fabrication and application of fractional-order capacitors

2019
The fractional–order capacitors add an additional degree of freedom over conventional capacitors in circuit design and facilitate circuit configurations that would be impractical or impossible to implement with conventional capacitors. We propose a generic strategy for fractional-order capacitor fabrication that integrates layers of conductive ...
