Abstract
A thin film inductor according to one embodiment includes one or more arms; one or more conductors passing through each arm; a first ferromagnetic yoke wrapping partially around the one or more conductors in a first of the one or more arms, the first ferromagnetic yoke comprising a magnetic top section, a magnetic bottom section, and via regions positioned on opposites sides of the one or more conductors in the first of the one or more arms, wherein the magnetic top section and magnetic bottom section are coupled together through a low reluctance path in the via regions; and one or more non-magnetic gaps between the top section and the bottom section in at least one of the via regions. Additional systems and methods are also provided.
