Abstract
This paper adopts the fractional calculus to model a pn semiconductor diode under sinusoidal operation. The electrical impedance spectroscopy and the describing function techniques are used for measuring the device impedance. The experimental data is approximated by means of fractional-order models. The results demonstrate that the proposed approach describes the diode impedance using a limited number of parameters, while highlighting relevant dynamic characteristics that are overlooked by classical models.
