Bessel filters using simulated inductor

Abstract

The use of passive component namely the inductor in analog circuits is very difficult at low frequencies, because the size of the inductors becomes very large and the fabrication of inductors in IC is also not possible to suite with the modern advancement of IC technology. In this paper, the method of simulating the passive component L using Generalized Impedance Converter (GIC) is presented. This simulated inductor is applied for the realization of Bessel filters. The circuit simulation is done using PSPICE. The design and frequency response of low pass, high pass and all pass filters are also presented.
