Abstract: In one aspect, an angle sensor includes a first plurality of magnetoresistance elements located at a first location on an axis and a second plurality of magnetoresistance elements located at a second location on the axis. The first plurality of magnetoresistance elements includes a first one or more magnetoresistance elements each having a reference direction in a first direction; and a second one or more magnetoresistance elements each having a reference direction in a second direction. The second plurality of magnetoresistance elements includes a third one or more magnetoresistance elements each having a reference direction in the first direction, and a fourth one or more magnetoresistance elements each having a reference direction in the second direction. The angle sensor senses movement of a magnetic target, and the magnetic target is a ring magnet or a single pole magnet.
