Basic Analog Circuit Building Blocks Using CCs and Application of CCs in Impedance Synthesis - Current Conveyors: Variants, Applications and Hardware Implementations - page 127

Lastly, it is worth pointing out that Current-controllable resistances can also be
realized by Current Conveyors as shown by Saaid and Fabre in [ 82 ], however, the
circuits of this kind are formally dealt with in a subsequent chapter of this mono-
graph (Chap. 9 ).
Concluding Remarks
It was demonstrated that CC-based realisations of inverting/non-inverting/
instrumentation amplifiers, make it possible to eliminate the gain and band-
width conflict prevalent in op-amp based circuits. Furthermore, inverting/
non-inverting/differential integrators/differentiators all can be realized with
the least possible number of passive components in both VM and
CM. Furthermore, positive/negative impedance converters/inverters can be
implemented exhibiting the same features. A major application of CCs has
been in the realization of impedance simulation particularly in the realization
of floating impedances wherein it becomes possible to realize a variety of
floating impedances without requiring any component matching condition(s)
- a feat which is impossible to be achieved with op-amp-based circuits. From
a vast amount of literature available on this topic, some notable grounded
impedance and floating impedance simulators using CCs, including the
voltage controlled impedances, were outlined and some ideas for further
work in these areas have been suggested.
