Abstract
A spiral inductor includes a spiral trace and a plurality of first projections extending along a first edge of the spiral trace. The spiral inductor may further include a plurality of second projections extending along a second edge of the spiral trace, the second edge being opposite the first edge.
Claims17
A spiral inductor comprising:
- a spiral trace;
- and
- a plurality of first projections extending along a first edge of the spiral trace, wherein the plurality of first projections extend horizontally from the first edge of the spiral trace,
- a plurality of second projections extending along and horizontally from a second edge of the spiral trace, the second edge being opposite the first edge,
- wherein each of the plurality of first projections extends from the first edge by a first length, wherein each of the plurality of first projections is separated from an adjacent first projection by a first distance, wherein a ratio of the first length to the first distance is at least 1:1,
- wherein each of the plurality of second projections extends from the second edge by a second length, wherein each of the plurality of second projections is separated from an adjacent second projection by a second distance, wherein a ratio of the second length to the second distance is at least 1:1, and
- wherein the spiral trace has a first turn and a second turn, wherein the plurality of first projections along the first turn are interlaced with the plurality of second projections along the second turn by a third length to create capacitive coupling between the plurality of first projections and the plurality of second projections.

A co-spiral inductor comprising:
- a first spiral trace;
- and
- a second spiral trace disposed over the first spiral trace,
- wherein each of the first spiral trace and the second spiral trace includes a plurality of first projections extending along a first edge of the spiral trace and a plurality of second projections extending along and horizontally from a second edge of the spiral trace, the second edge being opposite the first edge, and
- wherein each of the first spiral trace and the second spiral trace has a first turn and a second turn, wherein the plurality of first projections along each of the first turns are interlaced with the plurality of second projections along each of the second turns by a first length to create capacitive coupling between the plurality of first projections and the plurality of second projections of the first spiral trace and the second spiral trace.
