from where one can easily work out that, subject to different input conditions /
selections, it would be possible to realize all the five standard functions with tuning

.
In Fig.

, another novel application of the CCCC-TA in realizing an
electronically-controllable grounded inductor is shown, which employs only one
CCCC-TA along with a grounded capacitor as advantageous for IC implementa-
tion. The realized inductance value is given by
