Abstract
Inducting devices having a patterned ground shield with ribbing in an integrated circuit. In one embodiment, an inducting device comprises conductive turns to conduct current, a shield layer and a plurality of ribs. The shield layer is formed a select distance from the conductive turns. The shield layer is patterned into sections of shield to prevent eddy currents. The plurality of ribs are formed from a conductive layer that is positioned between the conductive turns and shield layer. Each rib is electrically coupled to a single associated section of shield. Moreover, each rib is more conductive than its associated section of shield to provide a less resistive current path than its associated section of shield.
