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.
