Abstract
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.
