Abstract
A varainductor includes a signal line over a substrate. The varainductor further includes a first ground plane over the substrate. The varainductor further includes 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. The varainductor further includes a first transistor configured to selectively electrically connect the first ground plane to the first floating plane. The varainductor further includes 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 connected to a gate of the second transistor.
