Abstract

An example circuit includes a coil structure located on at least a first layer of an integrated circuit (IC); and a circuit component comprising conduction paths. The conduction paths are located on one or more layers separate from the first layer and the first layer and the one or more layers form parallel planes. The conduction paths of the circuit component are oriented to avoid eddy currents in the conduction paths caused by an electric current through the coil structure and form a patterned shield. At least some of the conduction paths define an area, and the coil structure is located within the defined area.
