Abstract:
1. A method to convert a source voltage having a first value to a load voltage having a second value that differs from the first value, comprising: providing a voltage regulator circuit comprised of a plurality of transistor switches coupled to the source voltage and to a slab inductor having a length, a width and a thickness, the slab inductor being coupled between the plurality of switches and a load and sourcing a load current during operation of the plurality of switches; and operating the voltage regulator circuit to provide the load voltage at the load current, where the slab inductor is coupled to the load through a power grid that comprises one conductor, and further comprising shielding the slab inductor from a return current by providing an aperture in the power grid that underlies a location where the slab inductor is disposed above the power grid.
