Novel grounded parallel immittance simulator topologies employing single OTRA

Abstract

In this study, six novel grounded parallel immittance simulator topologies employing single OTRA are proposed. Some of the presented topologies require fewer passive components than the counterparts in the literature. The proposed new immittance simulator topologies provide further possibilities for the designers in the realization of filters, oscillators and cancellation of parasitic elements. The performance of the proposed immittance simulators is demonstrated on a current-mode multifunction filter. PSPICE simulation results are included to verify theory.
