Abstract
An integrated circuit includes an inductor that includes a first set of conductive lines in a first metal layer, and is over a substrate, and a guard ring. The guard ring includes a first conductive line in a second metal layer, and extending in a first direction, a second conductive line extending in a second direction, and a first staggered line coupled between the first conductive line and the second conductive line. The first staggered line includes a second set of conductive lines in the second metal layer, and extends in the first direction, a third set of conductive lines in a third metal layer, and extends in the second direction, and a first set of vias coupling the second and third set of conductive lines together. All metal lines in the third metal layer that are part of the guard ring extend in the second direction.
