Inverting Third Generation Current Conveyors
Extending the concept of CCIII further, inverting CCIII of both polarities, namely,
ICCIII+ and ICCIII
were introduced by Sobhy and Soliman in [
31
]. The ICCIII
elements are characterized by I

are particularly attractive in realizing V to I
converters, integrators, filters and oscillators- all providing electronic control of
various parameters.
