Abstract:
A varainductor includes a spiral inductor over a substrate, the spiral inductor comprising a ring portion. The varainductor further includes a ground ring over the substrate, the ground ring surrounding at least the ring portion of the spiral inductor and a floating ring over the substrate, the floating ring disposed between the ground ring and the spiral inductor. The varainductor further includes an array of switches, the array of switches is configured to selectively connect the ground ring to the floating ring.
