Classification: CPC G  H | IPC G  H

Claim 8:
9. A method comprising:
forming a sense resistor comprising:
a plurality of parallel-coupled resistor elements, coupled between a first electrical node and a second electrical node;
a plurality of positive voltage sense points, each positive voltage sense point configured to sense a first voltage at the first electrical node; and
a plurality of negative voltage sense points, each negative voltage sense point configured to sense a second voltage at the second electrical node;

combining the plurality of positive voltage sense points into a single positive sense terminal with a first passive combination network;
combining the plurality of negative voltage sense points into a single negative sense terminal using a second passive combination network; and
arranging the first passive combination network and the second passive combination network 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.
