Abstract
A magnetic field sensor for sensing a movement of a target object an include a substrate having a major planar surface and three or more magnetic field sensing elements disposed upon the major planar surface of the substrate. The three or more magnetic field sensing elements can have respective major response axes, each major response axis parallel to the major planar surface of the substrate. The three or more magnetic field sensing elements comprise first and third magnetic field sensing elements and a second magnetic field sensing element disposed between the first and third magnetic field sensing elements. A first spacing between the first and second magnetic field sensing elements is less than a second spacing between the second and third magnetic field sensing elements. No other magnetic field sensing elements are disposed between the first and third magnetoresistance elements.
