Simulation of Inductors and Other Types of Impedances Using CFOAs

Part of the Analog Circuits and Signal Processing book series (ACSP)


After briefly reviewing some prominent and well-known op-amp RC circuits for grounded and floating inductance simulation and pointing out the drawbacks and limitations thereof, a number of novel grounded and floating impedance simulation circuits realized with CFOAs have been described and their merits have been outlined. A number of CFOA-based generalized positive/negative, grounded/floating impedance simulators have also been described. It is shown that CFOA-based impedance simulation circuits offer a number of significant advantages over their VOA-based counterparts. The applications of the CFOA-based simulators in the design of second order and higher order filters have been suggested. A number of CFOA-based voltage controlled impedance simulation circuits including two generalized floating linear VCZ configurations have also been highlighted.
