Realization of Foster Structure-Based Ladder Fractor with Phase Band Specification
Circuits, Systems, and Signal Processing, 2019This paper presents Foster I and Foster II realizations of fractors using RC ladders while meeting five different specifications together, i.e., exponent, coefficients, upper and lower limits of constant phase zone, and phase band. The work mainly focusses on achieving the specified phase band to circumvent the present limitation of state-of-the-art. A

Characterization, packaging and application of a wide CP zone CNT based fractor
AEU - International Journal of Electronics and Communications, 2020Abstract This paper presents fabrication and characterization of fractors or fractional order (FO) elements with wide constant phase zones (10−2–105 Hz). They are realized with carbon nanotube (CNT) and polyimide composite coated electrodes and ionic gels. A thorough study has been carried out on variations of their electrical parameters with respect

Effect of Electrolytic Capacitors on the Performance of Multicomponent Fractors
2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020To realise a fractor, several integer order approximation methods are available. These are also called as multicomponent fractors because they require a chain network of resistors and capacitors for their hardware implementation. Generally the values of these components obtained from the approximation algorithms are not standard.

Realization of a carbon nanotube based electrochemical fractor
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015A fractor or a fractional order element should show a constant phase (CP), between ±90° (except 0°) at any frequency, theoretically. However, all the practical realization of single component fractor have limitation in their CP zone. Not many single-component-fractors have been reported having CP zone more than a decade.

Design and Performance Study of Dynamic Fractors in Any of the Four Quadrants
Circuits, Systems, and Signal Processing, 2015A fractor is a simple fractional-order system. Its transfer function is $$1/Fs^{\alpha }$$1/Fs?; the coefficient, F, is called the fractance, and $$\alpha $$? is called the exponent of the fractor. This paper presents how a fractor can be realized, using RC ladder circuit, meeting the predefined specifications on both F and $$\alpha $$?.

Order-Frequency Characteristics of a Promising Circuit Element: Fractor
Journal of Circuits, Systems and Computers, 2016This paper mainly discusses the order-frequency characteristics of a promising circuit element: fractor. The concept of fractance, as the fractional-order impedance of a fractor, arose following the successful synthesis of a fractional differentiator or integrator in an analog circuit.

Realization and study of a fractional order resonator using an obtuse angle fractor
2016 IEEE Students’ Technology Symposium (TechSym), 2016This paper discusses development of a fractional order resonator (FOR) using a single fractor, a capacitor and a resistor. The said fractor is an obtuse angle type inductive fractor and inclusion of such fractor makes the Q-factor of this FOR infinite (theoretically). Besides, the proposed FOR is tunable; varying the fractance, the resonating frequency
