Abstract
A field-sensor device comprises a reference field sensor biased with a reference current. The reference field sensor provides a reference sensor signal in response to a field, and a calibrated field sensor biased with an individually adjustable current and providing a calibrated sensor signal in response to the field. A control circuit controls the adjustable current bias of the calibrated field sensor at a calibrated current different from the reference current so that the calibrated field sensor provides a calibrated sensor signal substantially equal to the reference sensor signal in response to a common field. The field sensor device is arranged to be exposed, when in a calibration mode, to a uniform calibration field and, when in operational mode, to an operational field being a field gradient.
