1. A current sensor, comprising:

  • a conductive element with at least three separate terminal areas and a common conductive area, wherein each of the at least three separate terminal areas is connected separately to the common conductive area to guide separately a current applied to the respective terminal area into the common conductive area; and

    at least two magnetic field sensors arranged at different geometric positions adjacent to the common conductive area, wherein each of the at least two magnetic field sensors is configured to sense a magnetic field component of the current flowing into the common conductive area to provide a sensor signal based on the sensed magnetic field component;

    wherein the at least two magnetic field sensors are arranged adjacent to the common conductive area such that the current sensor can measure separately the currents guided by the at least three separate terminal areas into the common conductive area.
