Folded conical inductor

A design structure tangibly embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit, the design structure comprising:

• a first spiral structure, located on a first metal layer, having a first outer-spiral electrically conductive track and a first inner-spiral electrically conductive track separated from the first outer-spiral electrically conductive track by a first dielectric material;
• and
• a second spiral structure, located on a second metal layer, having a second outer-spiral electrically conductive track and a second inner-spiral electrically conductive track, the first outer-spiral electrically conductive track electrically coupled to an input of the second outer-spiral electrically conductive track and the first inner-spiral electrically conductive track electrically coupled to an output of the second inner-spiral spiral electrically conductive track, wherein the second outer-spiral electrically conductive track comprises non-overlapping conductive regions and overlapping conductive regions with the first outer-spiral electrically conductive track and wherein the second inner-spiral has conductive regions that are entirely non-overlapping with the first inner-spiral electrically conductive track.
