Abstract

This paper presents a Second Order Notch/All pass filter based on Operational Transresistance Amplifier (OTRA). It uses two OTRA's and five resistances. To add electronic tunability, the filter uses a capacitor array that can be controlled by switches. The switches are also used to provide inverting and non inverting Notch/All pass as response. This adds flexibility in phase response of all pass filter. The notch/all pass configuration is a modified extension of the Delyiannis-Friend circuit. Through the addition of a second active block which basically acts as a summer for the input voltage and the output of the first OTRA block. The functionality of the proposed filters is verified through SPICE simulations using CMOS based implementation of OTRA. The power supply for the implementation is 1.5V and is based on 0.5 submicron technology.
