CFOA-based fractional-order oscillator design and analysis with NILT method

Abstract

In this paper, a fractional-order oscillator based on current-feedback operational amplifiers (CFOAs) is presented. The design parameters such as frequency of oscillation, condition of oscillation, and stability criteria are given in general. To demonstrate the effect of fractional-order on design parameters, some special cases are shown. The numerical results of different fractional-order oscillators are presented to validate the analytical formulas.
