Nonlinear charge-voltage relationship in constant phase element

2020Allagui A.Das S.Elwakil A.S.Fouda M.E.JournalPsychalinos C.Radwan A.G.

The constant phase element (CPE) or fractional-order capacitor is an electrical device that has an impedance of the form Z(s)=1/C?s?, where C? is the CPE parameter and ? is a fractional dispersion coefficient of values between 0 and 1
