Abstract: An inductor includes a conductive track forming at least three inductor turns. The conductive track has a plurality of track sections. The inductor also includes at least two groups of crossing points, each crossing point comprising a location at which the conductive track crosses over itself. The crossing points of each group collectively reverse the order of at least some of the track sections in the inductor, such that inner track sections of the conductive track cross over to become respective outer track sections, and such that outer track sections of the conductive track cross over to become respective inner track sections.

Abstract: A symmetrical inductor having at least one inductor turn. Each inductor turn has a plurality of separate conductive paths having substantially equal inductance. The inductor also comprises a plurality of crossing points. At each crossing point, some of the conductive paths within a given inductor turn cross over each other to change the order in which they appear within the inductor turn.
