Optimal Design for Realizing a Grounded Fractional Order Inductor Using GIC

Abstract

This paper addresses the issue of the optimal design of a grounded fractional order inductor using a generalized impedance converter. The nonidealities of the op amps have been taken into account while formulating the approximate frequency characteristics of the fractional order inductor for both Type-I and Type-II realizations. Based on these formulations a set of design guidelines is proposed to achieve minimum phase and magnitude errors for the realized fractional inductor. The minimization conditions have been validated by several simulation and experimental results.
