Varainductor having ground and floating planes and method of using

A varainductor comprising:

• a signal line over a substrate;
• a first ground plane over the substrate;
• a first floating plane over the substrate, wherein the first floating plane is between the first ground plane and the signal line, and the first floating plane is a same distance from the substrate as the first ground plane;
• and
• a first transistor configured to selectively electrically connect the first ground plane to the first floating plane;
• and
• a second transistor configured to selectively electrically connect the first ground plane to the first floating plane, wherein a gate of the first transistor is electrically separated from a gate of the second transistor.

A method of controlling varainductor comprising:

• receiving a voltage on a signal line;
• receiving at least one control signal;
• and
• operating a plurality of switches in response to the received at least one control signal, wherein the operating the plurality of switches comprises selectively electrically connecting a first ground plane to a first floating plane, wherein the first floating plane is between the first ground plane and the signal line, and the first floating plane is a same distance from a substrate as the first ground plane.
