Abstract
An integrated circuit comprises an inductor over a substrate and a guard ring surrounding the inductor. The guard ring comprises a plurality of first metal lines extending in a first direction and a plurality of second metal lines extending in a second direction. The second metal lines of the plurality of second metal lines are each coupled with at least one first metal line of the plurality of first metal lines. The guard ring also comprises a staggered line comprising a connected subset of at least one first metal line of the plurality of first metal lines and at least one second metal line of the plurality of second metal lines. The first metal lines of the plurality of first metal lines outside of the connected subset, the second metal lines of the plurality of second metal lines outside of the connected subset, and the staggered line surround the inductor.
