1. An angle sensor comprising:
a first plurality of magnetoresistance elements located at a first location on an axis, the first plurality of magnetoresistance elements comprises:
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; and
a second plurality of magnetoresistance elements located at a second location on the axis, the second plurality of magnetoresistance elements comprises:
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,
wherein the angle sensor senses movement of a magnetic target, and
wherein the magnetic target is a ring magnet or a single pole magnet; and
a first bridge comprising a first leg comprising one of the magnetoresistance elements of the first one or more magnetoresistance elements and one of the magnetoresistance elements of the third one or more magnetoresistance elements.
