On The Realization of Grounded RL/RC Parallel Type Simulator

Abstract

An actively grounded RL/RC parallel type impedance simulator is presented. It contains two differential voltage to current converters (DVTCs) as an active element and three passive elements, and can simulate RL or RC parallel-type impedance by the proper selection of the external passive elements. The effect of the DVTC non-idealities on the realized simulator is also analyzed mathematically. The usability of the proposed circuit has been shown on the realizations of active second-order voltage mode highpass-and lowpass-filter. PSPICE simulation using TSMC 0.25-$\mu$m CMOS technology is performed to demonstrate the behavior of the proposed simulator circuit and its filter applications.
