  • Publication number: 20110076979
    Abstract: A shielded differential inductor forms a high quality factor (high-Q) inductor that is configured to attenuate frequency spurs and/or noise from magnetic coupling generated by electrical structures on or off of a substrate as well as interference received by other components from magnetic coupling generated by the inductor. The shielded differential inductor includes a differential inductor and a shield that substantially isolates the electrical field between the inductor and the substrate to reduce substrate current loss. The shield includes sets of finger structures that extend beyond the width of the inductor and a hub and spoke configuration of ground conductors that connect the sets of finger structures to ground.
