1. An apparatus comprising a primary three-dimensional (3D) multi-turn inductor and a substrate, wherein:
the primary 3D multi-turn inductor resides in the substrate;
the primary 3D multi-turn inductor has a shape corresponding to a first two-dimensional (2D) lobe and is wrapped around a cube, wherein the first 2D lobe has no internal intersections;
the primary 3D multi-turn inductor extends over each facet of the cube; and
the primary 3D multi-turn inductor comprises only eight connecting ends located at eight edges of the cube, respectively, such that only one of the eight connecting ends is located at a corresponding one of the eight edges of the cube, wherein the primary 3D multi-turn inductor turns directions only at each of the eight connecting ends, and turns directions only one time at each of the eight edges of the cube.
