A magnetic field sensor for sensing an absolute position of a target object can include a first one or more magnetic field sensing elements disposed proximate to a first portion of the target object, the first one or more magnetic field sensing elements operable to generate a first magnetic field signal responsive to the movement of the first portion; a second one or more magnetic field sensing elements disposed proximate to a second portion of the target object, the second one or more magnetic field sensing elements operable to generate a second magnetic field signal responsive to the movement of the second portion; a position detection module coupled to use the first and second magnetic field signals to generate a position value indicative of the absolute position; and an output format module coupled to receive the position value and to generate a position signal from the magnetic field sensor indicative of the absolute position.

Magnetic field sensor for detecting an absolute position of a target object

A magnetic field sensor for sensing an absolute position of a target object can include one or more magnetic field sensing elements disposed proximate to a mechanical intersection of first and second portions of a target object, wherein the one or more magnetic field sensing elements are operable to generate a first magnetic field signal responsive to the movement of both the first and second portions. The magnetic field sensor can also include a position detection module operable to use the first magnetic field signal to generate a position value indicative of the absolute position. The magnetic field sensor can also include an output format module coupled to receive the position value and to generate an output signal from the magnetic field sensor indicative of the absolute position.
