About implementing an inductor by the means of gyrators

Abstract

Take into account the entrance equivalentimpedance of gyrators, by connecting a condenser tooutput is possible simulate a lossless inductor,which can be grounded inductor or floatinginductor. The gyrators behavior of a class of twoportsstructured on operational amplifiers andresistors is studied. The paper presents some aspectsregarding performances characteristics of gyratorswith different circuit topology. In order to verify thetheoretical predictions, the analytical inductivitiesare linked with the experimental one numerical bythe means of a PSpice simulation.
