Novel Lossless Grounded and Floating Inductance Simulators Employing a Grounded Capacitor Based on CC-CFA

Abstract

Simulation of inductors has been a very popular area of analog circuit research and the alternative choice for realizing inductor-based circuits in integrated circuits. In this paper, lossless, grounded and floating inductor topologies using current-controlled-current-feedback amplifier (CC-CFA) with single grounded capacitor are presented. The proposed topologies can be tuned electronically by changing the biasing current of the CC-CFA. Two topologies for grounded inductor simulator employ two CC-CFA and one grounded capacitor. One topology for floating inductor simulator employs three CC-CFA and one grounded capacitor. The performance of the grounded and floating inductor simulators are demonstrated on resonant circuits. The theoretical analysis is verified by PSPICE simulation results.
