RC models of a constant phase element

International Journal of Circuit Theory and Applications, 2011
SUMMARYThe paper describes models of a constant‐phase element consisting of passive R and C components. The models offer any input impedance argument (phase) between −90° and 0° over a selectable frequency band covering several decades. The design procedure makes it possible to choose values of average phase, phase ripple, frequency bandwidth, and ...

On Interpretation of Constant-Phase Elements

ECS Meeting Abstracts, 2016
Electrical circuits invoking constant-phase elements (CPE) are often used to fit impedance data arising from a broad range of experimental systems. The CPE is often used simply as a way to improve the fit of a model to impedance data, justified by a vague assertion that a distribution of time constants is present in the system under investigation.

On the physical interpretation of constant phase elements

Solid State Ionics, 2009
Abstract Complex impedance spectra of ion-conducting lithium borate network glasses are used to study the deformed shape of impedance semicircles which are usually described by a parallel circuit of an ohmic resistor and a phenomenological Constant Phase Element (CPE). Based on the Concept of Mismatch and Relaxation (CMR) of Funke et al.

Designing constant phase elements of complement order

Analog Integrated Circuits and Signal Processing, 2018
Once designing analogue fractional-order function blocks, the capacitive and/or inductive fractional-order elements (FOEs), also referred to as constant phase elements, being defined with their fractional order $$\alpha$$

Experimental technique for estimating the dispersion coefficient of a constant phase element

2011 20th European Conference on Circuit Theory and Design (ECCTD), 2011
We report an experimental technique for estimating the dispersion coefficient α of a constant phase element (CPE). The method employs using a setup to excite the impedance under consideration via a periodic triangle-wave current I(t). Measuring the 50% rise time of the developed voltage V (t) then enables finding α using a pre-calculated Table ...

On the efficient simulation of electrical circuits with constant phase elements: The Warburg element as a test case

International Journal of Circuit Theory and Applications, 2018
SummaryThe constant phase Element (CPE) concept naturally emerges as a model for describing a range of electrical phenomena where ionic diffusion is involved. We suggest a new method for modelling the transient behavior of electrical circuits that contain CPE elements.
