Abstract
Aspects generally relate to adjusting, or lowering, the Q of an inductor. In one embodiment, an integrated circuit includes an inductor and a conductive closed ring inside a periphery of the inductor. In another embodiment, there can be a plurality of closed rings inside the periphery of the inductor. The conductive closed rings are magnetically coupled to the inductor to adjust the Q.
