Narrow Results

It is well known that a floating inductor circuit is realized from a grounded inductor circuit by replacing the operational amplifier by a floating operational transconductance amplifier. This idea is extended to transform current conveyor grounded inductors to floating inductors by replacing the current conveyor by the recently introduced floating current conveyor. Several examples are considered and simulation results are given to support the theory. Although the paper is partially a review in nature it includes several new realizations of floating inductors.

In a recent paper published in this journal, Soliman presented the methods of transformation of grounded inductors to floating inductors using operational floating amplifiers and floating second generation current conveyors. The purpose of this note is to bring on record the present author's earlier works on the same topic published about 24 years back which are closely related to the work reported in Soliman's paper but have not been cited therein.

Recently this author published a paper¹ discussing the transformation of grounded inductors to floating inductors using operational floating amplifier (OFA) or floating current conveyor (FCCII). The author classified the paper as a partially review paper as stated in the abstract and in the introduction of Ref. 1 The author states in the abstract that: It is well known that a floating inductor circuit is realized from a grounded inductor circuit by replacing the operational amplifier by a floating operational transconductance amplifier. This idea is extended to transform current conveyor grounded inductors to floating inductors by replacing the current conveyor by the recently introduced floating current conveyor.
