Claim Text:
1. A magnetic field angle sensor comprising: a magnet rotatable about an axis of rotation within an angular range; a substrate arranged proximate the magnet such that a projection of the axis of rotation intersects the substrate and comprising a first surface arranged perpendicularly with respect to the axis of rotation; at least three magnetic field sensor elements on the first surface of the substrate, the at least three magnetic field sensor elements distributed evenly within the angular range along a curve contained within a perimeter of the first surface and sensitive to magnetic field components parallel to the first surface of the substrate, wherein at least one of the at least three magnetic field sensor elements is sensitive to a magnetic field component of a first direction and at least one other of the at least three magnetic field sensor elements is sensitive to a magnetic field component of a second direction, the first direction being different from the second direction; and circuitry coupled to the at least three magnetic field sensor elements, the circuitry configured to:
