RESISTOR WITH EXPONENTIAL-WEIGHTED TRIM

An electronic device, e.g. a trimmable resistor, includes a plurality of fused resistors, each fused resistor including one or more doped resistive regions formed in a semiconductor substrate. The doped resistive regions may be thermistors. Each fused resistor further includes a corresponding one of a plurality of fusible links. A first terminal of each of the fused resistors is connected to a first terminal of the corresponding fusible link. First and second interconnection buses are located over the substrate, with the first interconnection bus connecting to a second terminal of each of the fused resistors, and the second interconnection bus connecting to a second terminal of each of the fusible links. The plurality of fused resistors have resistance values that form an exponential progression.
