Abstract
An apparatus may include a sense resistor comprising a plurality of parallel-coupled resistor elements, a plurality of positive voltage sense points, and a plurality of negative voltage sense points. A first passive combination network may be configured to combine the plurality of positive voltage sense points into a single positive sense terminal and a second passive combination network may be configured to combine the plurality of negative voltage sense points into a single negative sense terminal. The first passive combination network and the second passive combination network may be arranged such that a sense voltage is measurable between the single positive sense terminal and the single negative sense terminal and a dependence of the sense voltage on a variation in current density in the parallel-coupled resistor elements is minimized.
