Claim Text:
1. A current sensor package configured to sense a primary current flowing in a primary conductor of a substrate, the current sensor package comprising: a calibration current provider configured to provide a calibration current for a calibration conductor of the substrate, wherein the calibration conductor and the primary conductor are arranged in a defined spatial relation to each other on the substrate, and wherein the primary conductor and the calibration conductor are electrically isolated from each other; a magnetic field sensor configured to sense a magnetic field of the primary current flowing in the primary conductor to provide a primary sensor signal, and further configured to sense a magnetic field of the calibration current flowing through the calibration conductor to provide a calibration sensor signal; and a controller configured to receive the primary sensor signal and the calibration sensor signal, and configured to calibrate the primary sensor signal based on the calibration sensor signal and the defined spatial relation between the primary conductor and the calibration conductor.
