Magnetic-field sensor arrangement and method of calibrating a magnetic-field sensor of a magnetic-field sensor arrangement

Magnetic-field sensor arrangement comprising:

• a magnetic-field sensor configured to provide a sensor output signal on the basis of a magnetic field acting on the sensor;
• an excitation-conductor array comprising a plurality of selectively driveable excitation conductors arranged at a distance from the magnetic-field sensor;
• a driver for selectively driving the excitation conductors so as to generate different magnetic test fields in the magnetic-field sensor in different drive states by driving a different excitation conductor, and so as to generate a set of detected output signal values of the magnetic-field sensor in accordance with the different drive states;
• and
• an evaluator configured to provide different parameter sets comprising comparison output signal values for the different drive states, the parameter sets representing variations of the architecture of the magnetic-field sensor comprising the excitation-conductor array, and further configured to determine, on the basis of the set of detected output signal values of the magnetic-field sensor, that parameter set whose comparison output signal values exhibit a best match with the set of detected output signal values.
