Design of Bessel High Order All Pass Filter Based on AN OTRA

Abstract

This paper features a single-input single-output (SISO). The suggested circuit is depend on OTRA which is referred as operational transresistance amplifier. and OTRA recommended on the parameters of its increasing slew rate and large bandwidth as compared to conventional circuit containing operational amplifier. In this paper Bessel Higher order All Pass filter structure are described and their simulation is carried out in PSPICE with the help of 0.5μm CMOS technology and simulation result follows the theoretical approach.
