Abstract
An integrated circuit includes an inductor over a substrate and a guard ring surrounding the inductor. The guard ring includes a first staggered line, a first metal line extending in a first direction and a second metal line extending in a second direction different from the first direction. The first staggered line has a first end coupled to the first metal line, and a second end coupled to the second metal line. The first staggered line includes a first set of vias, a first set of metal lines in a first metal layer and a second set of metal lines in a second metal layer different from the first metal layer. The first set of vias coupling the first set of metal lines with the second of second metal lines.
