Sensor (2000), comprising: a magnet (2004); first, second, third and fourth sensor elements disposed in relation to the magnet (2004); and an analog signal processing module (2008) for processing output signals of the first, second, third and fourth sensor elements and generating first and second difference signals for minimizing effects of positional misalignments of the first, second, third and fourth sensor elements with respect to the magnet by maximizing a quadrature ratio of the first and second difference signals. |
