Abstract
An apparatus, comprising: a substrate; a switching device that is formed over the substrate, the switching device including a gate layer, a source layer, and a drain layer; a first layer of dielectric material that is formed over the switching device; a first contact member that is electrically coupled to one of the gate layer, the source layer, and the drain layer, the first contact member being formed of at least one electrically-conductive material, the first contact member extending through the first layer of dielectric material; a plurality of first magnetic field sensing elements, the plurality of first magnetic field sensing elements being arranged to at least partially surround the first contact member, the plurality of first magnetic field sensing elements being arranged, at least in part, to form a sensing circuit for measuring a level of electrical current through the first contact member.
