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 ...

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 $$\alpha$$

Constant-Phase-Element Behavior Caused by Resistivity Distributions in Films

Journal of The Electrochemical Society, 2010
CPE behavior may be attributed to the distribution of physical properties in films, in the direction normal to the electrode surface. Numerical simulations were used to show that, under assumption that the dielectric constant is independent of position, a normal power-law distribution of local resistivity is consistent with the Constant-Phase Element ...

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.

A constant phase element sensor for monitoring microbial growth

Sensors and Actuators B: Chemical, 2006
The construction and performance of a novel constant phase element (CPE) sensor for monitoring microbial growth has been reported in this paper. The signal conditioning circuit measures the changes in the phase angle of the impedance characteristics of the probe.

Emulation of a constant phase element using operational transconductance amplifiers

Analog Integrated Circuits and Signal Processing, 2015
The concept of emulating a constant phase element by an active scheme is presented in this work. Starting from a novel setup where the characteristics of the element could be easily derived, the emulation of the constant phase element is performed through a scheme that employs a differentiator and a voltage-to-current converter.
