Electronically tunable grounded inductance simulators and capacitor multipliers realization by using single Current Follower Transconductance Amplifier (CFTA)

Abstract

Inductance simulators and capacitor multipliers can be used to implement several electronic devices such as active filters, oscillators, cancellation of parasitic elements and phase shifting circuits. In this work, grounded inductance simulators (GISs) and grounded capacitor multipliers (GCMs) employing only one active component Current Follower Transconductance Amplifier (CFTA) and two passive elements (R and C) have been proposed. The aim of this work is to implement inductance simulators and capacitor multipliers using the minimum number of active elements which commercially available. The performance of the proposed circuits verified by using the LTSpice. To support the theoretical study, all simulation results are provided.
