Abstract
The invention relates to an angle sensor comprising at least two angle-offset anisotropic magnetoresistive sensor units comprising anisotropic magnetoresistive elements, in which the angle sensor comprises at least a device for increasing the anisotropic field strength of the sensor units. The invention also relates to a method of increasing the anisotropic field strength of a sensor unit of an angle sensor comprising magnetoresistive elements, in which a magnetic supporting field present in a preferred direction of the magnetoresistive elements is generated.
