1. An on-chip integrated variable inductor comprising:
- a signal line configured to conduct an electrical signal;
a first ground line positioned proximate to said signal line; and
at least one control unit disposed in a first current path connecting said first ground line with a ground potential, said at least one control unit configured to selectively open and close said first current path such that said signal line has a first inductance value when said first current path is open and a second inductance value when said first current path is closed to couple said first ground line with the ground potential.

Abstract
On-chip integrated variable inductors, methods of making and tuning an on-chip integrated variable inductor, and design structures embodying a circuit containing the on-chip integrated variable inductor. The inductor generally includes a signal line configured to carry an electrical signal, a ground line positioned in proximity to the signal line, and at least one control unit electrically coupled with the ground line. The at least one control unit is configured to open and close switch a current path connecting the ground line with a ground potential so as to change an inductance of the signal line.
