Abstract :
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. Experimental results are shown.
