Abstract: An electronic device (100), e.g . a trimmable resistor, includes a plurality of fused resistors having progressively larger resistance values. Optionally the resistance values form an exponential progression. Each fused resistor includes one or more doped resistive regions (410) formed in a semiconductor substrate, the doped resistive regions optionally being thermistors. A first terminal of each of the fused resistors is connected to a first terminal of a corresponding one of a plurality of fusible links (135). First (125) and second (130) interconnection buses are located over the substrate, with the first interconnection bus connected to a second terminal of each of the fused resistors, and the second interconnection bus connected to a second terminal of each of the fusible links.

Abstract: In a described example, a circuit (100) includes a sensor circuit (114) including multiple magnetic field sensors (118, 120) having respective sensor outputs. The magnetic field sensors (118, 120) are configured to provide magnetic field sensor signals at the respective sensor outputs representative of a measure of current flow through a conductive structure (104). A combiner interface (122) has combiner inputs and a combiner output. The combiner inputs are coupled to the respective sensor outputs. The combiner interface (122) is configured to provide an aggregate sensor measurement at the combiner output responsive to the magnetic field sensor signals, in which the aggregate sensor measurement is decoupled from magnetic fields generated responsive to the current flow through the conductive structure (104).
