Besides the op-amp based and operational transconductance amplifier-based gyrators and impedance simulators, the current-feedback operational amplifier (CFOA)-based circuits of these elements are attractive because of the commercial availability of the CFOA AD844 as an off-the-shelf IC. In this chapter, we consider the prominent circuits for realizing gyrators, lossless grounded inductance (GI)/ lossless floating inductance (FI) circuits as well as the more generalized generalized positive impedance converter/inverter and generalized negative impedance converter/inverter elements using CFOAs. It is found that a class of economic impedance simulation circuits based on the use of single CFOA offer the attractive features of single resistance tunability which is not available in the well-known single op-amp-based simulators of the same kind of impedances. A number of inductors and resonators using CFOA poles and a class of GI/FI simulators using a modified CFOA have also been included.

In this chapter, we present some prominent contributions made in the realization of gyrators and related impedances using electronic circuit building blocks of relatively more recent origin. Thus, we discuss the impedance synthesis using electronic circuit building blocks such as operational transresistance amplifier, Unity gain voltage follower/current follower, current-differencing buffered amplifier, voltage-differencing current conveyor (CC), current-differencing CC, current-differencing transconductance amplifier, current-follower transconductance amplifier, CC transconductance amplifier, voltage-differencing differential input buffered amplifier, voltage-differencing buffered amplifier and many others. Since the work on the use of all these building blocks done so far is by no means complete, we would also highlight what has not been attempted so far.

This chapter presents an overview of the significant contributions made on the realization of gyrators and various other kinds of impedances with particular emphasis on floating inductance simulation for which a specific form of nullor namely the so-called four-terminal-floating-nullor (FTFN) and the operational floating amplifier and somewhat similar appearing element, namely the operational mirrored amplifiers (OMAs) have been found to be particularly versatile. Most of the FTFN-based circuits described in this chapter can be practically implemented using commercially available integrated circuit (IC) current feedback op-amps (CFOAs; such as AD844 from Analog Devices Inc.), while the OMA-based circuits can be implemented with commercially available IC op-amps such as mA741 or LF356 in conjunction with mixed transistor arrays such as CA3096/LM3096.

K.W. Nay and A. Budak (1983) presented a technique employing JFETs and op-amps for obtaining voltage-controlled positive/negative resistance exhibiting wide dynamic range and low distortion. Here two new op-amp-JFET configurations are proposed, which not only realize voltage-controlled resistances but, unlike the Nay configuration, make it possible to realize voltage-controlled inductance and voltage-controlled capacitance elements, too. Experimental results are given to demonstrate the practical validity of the theoretical formulations. >
