Experimental studies on realization of fractional inductors and fractional-order bandpass filters

摘要

This paper presents the hardware realization and performance study of fractional inductors of order 02. The fractional inductors used in this work have been realized with the help of general impedance converter circuit and fractional capacitors. Impedance characterization of fractional inductors with different exponents has been carried out experimentally. Also a generalized approach to design a fractional-order bandpass filter is discussed in this work. The fractional-order bandpass filter consists of a series combination of a resistor, a fractional inductor of order 12, and a fractional capacitor of order 01. The performance of fractional-order bandpass filters has been studied and compared with corresponding integer-order filters through both experimentation and simulation.
