Abstract

Structures and methods for reducing physical space of two or three inductors while maintaining low magnetic coupling between the inductors are presented. According to one aspect, the inductors share their volume spaces and have (substantially) orthogonal far field magnetic vectors. According to another aspect, the inductors are fabricated on planar layers of a stacked structure that includes conductive and non-conductive layers. According to an additional aspect, a coil structure of one of the inductors passes through a volume space of another inductor. According to another aspect, coil structures of two of the inductors are interlaced. According to another aspect, relative placement of two coil structures of two inductors is based on a number of windings of one of the two coil structures above and below the other coil structure. According to another aspect, a shape of a coil structure of one inductor follows a near field magnetic vector of another inductor.
