Abstract

A sensor comprises an inductor for sensing an alternating current signal component of an observed signal. The inductor comprises a substrate, conductive traces associated with different layers of the substrate, and one or more conductive vias for interconnecting the plurality of conductive traces. A magnetic field sensor senses a direct current signal component of the observed signal. A first filtering circuit has a high-pass filter response. The first filtering circuit is coupled to the inductor to provide a filtered alternating current signal component. A second filtering circuit has a low-pass filter response. The second filtering circuit coupled to the magnetic field sensor to provide a filtered direct current signal component. A sensor fusion circuit determines an aggregate sensed current based on the filtered alternating current signal component and the filtered direct current signal component.
