Abstract:
A sensor minimizes effects of sensor element misalignment with respect to a magnet. In one embodiment, a sensor comprises a magnet, first, second, and third sensor elements positioned in relation to the magnet, and a signal processing module to process output signals from the first, second, and third sensor elements and generate first and second signals for minimizing effects of positional misalignment of the first, second, and third sensor elements with respect to the magnet by maximizing a quadrature relationship of the first and second signals.
