Abstract
A Hall sensor is disclosed. The Hall sensor comprises a first Hall element, configured to detect a component of a magnetic field in a first direction a using a sensitive area of the first Hall element. The Hall sensor further comprises a second Hall element, configured to detect a component of the magnetic field in a second direction b using a sensitive area of the second Hall element. The Hall sensor further comprises a conductor track, configured to generate a calibration magnetic field. The calibration magnetic field has a significant component on the sensitive area of the first Hall element in the second direction b. The calibration magnetic field further has a significant component on the sensitive area of the second Hall element in the first direction a.
