An InN/InGaN quantum dot nonlinear constant phase element

Japanese Journal of Applied Physics, 2022
Abstract InN/InGaN quantum dots (QDs) are found to establish a nonlinear constant phase element (CPE) response over a wide frequency range, measured by electrochemical impedance spectroscopy (EIS). The intrinsic surface donors together with the near-surface electron accumulation layer form the fractional capacitor.

Realization of a fractional-order RLC circuit via constant phase element [PDF]

International Journal of Dynamics and Control, 2021
AbstractIn the paper, a fractional-order RLC circuit is presented. The circuit is realized by using a fractional-order capacitor. This is realized by using carbon black dispersed in a polymeric matrix. Simulation results are compared with the experimental data, confirming the suitability of applying this new device in the circuital implementation of ...

Accurate Constant Phase Elements Dedicated for Audio Signal Processing [PDF]

Applied Sciences, 2019
This review paper introduces real-valued two-terminal fully passive RC ladder structures of the so-called constant phase elements (CPEs). These lumped electronic circuits can be understood as two-terminal elements described by fractional-order (FO) dynamics, i.e., current–voltage relation described by non-integer-order integration or derivation.
