Abstract
A spiral inductor includes a winding that includes a plurality of strands. The spiral inductor also includes a plurality of tracks where a first set of tracks is positioned adjacent to one another on a first of layer and a second set of tracks is positioned adjacent to one another on a second layer. Each of the plurality of tracks is capable of supporting one of the plurality of strands. The spiral inductor also includes a plurality of crossing segments to transpose one or more of the plurality of strands to each of the plurality of tracks, wherein each of the plurality of strands is electrically isolated from the other plurality of strands.
Claims29
A spiral inductor, comprising:
- a winding that includes a plurality of strands;
- a plurality of tracks, including a first set of tracks positioned adjacent to one another on a first of layer and a second set of tracks positioned adjacent to one another on a second layer, each of the plurality of tracks capable of supporting one of the plurality of strands;
- and
- a plurality of crossing segments to transpose one or more of the plurality of strands to each of the plurality of tracks, wherein each of the plurality of strands is electrically isolated from the other plurality of strands.
A spiral inductor, comprising:
- a winding that includes a plurality of strands;
- a plurality of tracks each vertically positioned to each other where each of the tracks is capable of supporting one of the plurality of strands at a position on the track;
- and
- a plurality of crossing segments to transpose one or more of the plurality of strands to each of the plurality of tracks, wherein each of the plurality of strands is electrically isolated from the other plurality of strands.
A magnetic component, comprising:
- a winding that includes a plurality of strands;
- a plurality of tracks, including a first set of tracks positioned adjacent to one another on a first of layer and a second set of tracks positioned adjacent to one another on a second layer, each of the plurality of tracks capable of supporting one of the plurality of strands;
- and
- a plurality of crossing segments to transpose one or more of the plurality of strands to a vertically adjacent track, wherein each of the plurality of strands is electrically isolated from the other plurality of strands.
