Novel two OTRA-based grounded immitance simulator topologies

Abstract

Three new operational transresistance amplifier (OTRA)-based grounded parallel immitance simulator topologies are presented. The proposed circuits use two OTRAs and require fewer passive components than most of the counterparts in the literature. The performance of the proposed immitance simulators is demonstrated on a fourth-order bandpass filter. PSPICE simulation results are included to verify theory.
