Abstract
Magnetic-field sensor arrangement comprises a magnetic-field sensor for providing a sensor output signal based on a magnetic field acting on the sensor; an excitation-conductor array including selectively driveable excitation conductors spaced from the magnetic-field sensor; a driver for selectively driving the excitation conductors to generate different magnetic test fields in different drive states by driving a different excitation conductor, and to generate a set of detected output signal values of the magnetic-field sensor according to the different drive states; and evaluator configured to provide different parameter sets including comparison output signal values for the different drive states and representing variations of the architecture of the magnetic-field sensor including the excitation-conductor array, and further configured to determine, based on 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.
