Abstract
Systems and methods for detecting the magnetic field created by a magnetic target. An arrangement of multiple magnetic field sensing elements and circuit elements configured to select and/or interpolate between the sensing elements to give enhanced performance and to compensate for external mechanical factors. The circuit arrangement is integrated on a single silicon chip to form an integrated circuit sensing device in one embodiment.
