Integrated circuit inductors achieve high quality factors by replacing a single conductive strand having a first cross-sectional area with a plurality of conductive strands having a combined second cross-sectional area that is smaller than the first cross-sectional area and a combined periphery that is greater than a periphery of the single conductive strand. The dimensions of the plurality of the conductive strands are greater than a skin depth at a desired operating frequency. This results in slightly higher dc resistance, but significantly lower ac resistance. The conductive strands are electrically coupled in parallel and extend side-by-side across an integrated circuit substrate. These strands include a plurality of crossing strand segments that enable the respective strand to be repeatedly transposed from one side of the plurality of strands to another side of the plurality of strands without electrical interruption. In some embodiments, the plurality of strands extend side-by-side in a horizontal plane that is at least substantially parallel to a surface of the integrated circuit substrate. In these embodiments, the crossing strand segments may be treated as cross-over/under strand segments.
