It was shown in [

] that with a
0it
would become a CCII. It may be noted that another generalized GCC, with all the
three pertinent h-parameters taken as non-unity and non-zero, was earlier proposed
in 1984 by Senani [
4
].
Another three port general conveyor was proposed by Biolek et al. in 2000 [
45
],
which were characterized by the hybrid matrix:

It was demonstrated that this generalization yields 12 distinctly different varieties
of Current Conveyors (namely, those of CCI, CCII, and ICCIII) as special cases by
assigning different possible values to the parameters
. In retrospection it
may be seen that it was nearly same as the generalized current conveyor introduced
by Senani in [
4
].

10.2.13 Universal Current Conveyor (UCC)
As an ultimate generalization of CCs, the so called
Universal Current Conveyor
(UCC) was proposed by Becvar et al. in 2000 in [
46
]. UCC is an eight terminal
building block characterized by the following matrix equation.
