1. An integrated circuit comprising:

  • a substrate;

    one or more semiconductor components on said substrate;

    a first electrically conductive layer on said substrate;

    a first insulating layer on said first electrically conductive layer;

    a layer of magnetic material on said first insulating layer and defining a closed-loop magnetic component positioned laterally adjacent said one or more semiconductor components;

    a second insulating layer on said closed-loop magnetic component;

    a second electrically conductive layer on said second insulating layer; and

    a first plurality of vertical electrical conductors connecting portions of said first and said second electrically conductive layers to define a first three-dimensional helical conductive structure surrounding at least a portion of said closed loop magnetic component laterally adjacent said one or more semiconductor components;

    at least one of said first and second electrically conductive layers also connecting the one or more semiconductor components.
