Abstract:
A sensor arrangement including a first and a second magnetoresistive sensor (1), comprising a main sensing element (2) with a main reference magnetization axis (3), for determining an angle between the main reference magnetization axis (3) and a magnetic field direction, characterized in that the main sensing element (2) is electrically connected to a first correction sensing element (6) with a first reference magnetization axis (9) and a second correction sensing element (8) with a second reference magnetization axis (10), the first (9) and the second (10) reference magnetization axes making correction angles &THgr; between 5Â° and 85Â° of opposite sign with the main reference axis (3), and in that the main reference magnetization axis (3) of the second sensor is rotated over a quarter period of a periodic output signal of the main sensing element of he first sensor and the correction angles being &frac18; period for each correction sensing element.
