Abstract
A current measurement system and a corresponding method are described, where the current measurement system includes a resistor structure having a sense resistor and a calibration resistor where a single metal layer of the resistor structure includes the sense resistor and the calibration resistor, calibration circuitry configured to provide a calibration current through the calibration resistor, and sense amplifiers configured to measure respective voltages across each of the calibration resistor and the sense resistor.
