Original Abstract Submitted
An integrated circuit includes an inductor that includes a first set of conductors in at least a first metal layer, and a guard ring enclosing the inductor. The guard ring includes a first conductor extending in a first direction, a second conductor extending in a second direction, and a first set of staggered conductors coupled to a first end of the first conductor and a first end of the second conductor. The first set of staggered conductors includes a second set of conductors in a second metal layer, a third set of conductors in a third metal layer and a first set of vias coupling the second set of conductors with the third set of conductors. The third metal layer is above the second metal layer. All metal lines in the second metal layer that are part of the guard ring extend in the first direction.
