Claim:
1. A three-dimensional multipath inductor, comprising: a plurality of turns disposed about a center region on at least two layers, the turns on the at least two layers having corresponding geometry therebetween; each of the plurality of turns being comprised of two or more segments that extend length-wise along the turns, the segments having positions that vary from an innermost position relative to the center region and an outermost position relative to the center region; at least one lateral cross-over configured to couple the segments of at least one turn on one layer with the segments on a turn on a same layer to form segment paths that have a same length for all segment paths in a grouping of segment paths on that same layer; and at least one vertical cross-over configured to couple the segments on different vertically stacked metal layers to have the segment groups with a same length for all segment paths based on vertical lengths.
