Abstract:
Embodiments relate to magnetic field angle sensors, including off-axis and on-axis sensors. In an embodiment, a magnetic field angle sensor comprises two sensor units, and each sensor unit comprises two sensor elements. The sensor units are spaced apart from one another and arranged proximate a magnet, wherein the two sensor elements of each sensor unit are responsive to the same magnetic field component induced by a magnet coupled to a shaft as the shaft rotates. In each sensor unit, a sum and a difference of the output signals of the two sensor elements can be calculated to determine a coarse estimation of a rotation angle, and a more refined estimation can be obtained by combining the coarse estimations of each sensor unit. In embodiment, the magnetic field angle sensor comprises a control unit or other circuitry to carry out this combining.

Claim (Index 1):
A magnetic field angle sensor comprising:\n a magnet rotatable about an axis of rotation; a plurality of sensor units arranged proximate the magnet and spaced apart from one another about the axis of rotation by (360 degrees/n), where n is the number of sensor units and is greater than or equal to 2, wherein each of the at least two sensor units comprises two magnetic field sensor elements spaced apart from each other, each responsive to the same magnetic field component induced by the magnet, wherein each of the at least two sensor units comprises a substrate associated with the respective sensor unit in which the two magnetic field sensor elements are provided and a respective package associated with the respective sensor unit; and circuitry coupled to the plurality of sensor units, wherein the circuitry is configured to receive output signals from each of the two magnetic field sensor elements for the at least two sensor units, and wherein the circuitry is configured to determine, for each of the at least two sensor units, a first coarse estimation of an angle of rotation of the magnet based on: a sum of output signals of the two magnetic field sensor elements of the respective sensor unit, and a difference of output signals of the two magnetic field sensor elements of the respective sensor unit, and wherein the circuitry is further configured to determine a second refined estimation of the angle of rotation of the magnet from the first coarse estimation of at least two of the sensor units.
