Abstract
A method of determining a linear or angular position of a magnetic sensor device relative to a magnetic source, or vice versa, the sensor device includes at least four magnetic sensor elements. The method involves the steps of: a) determining a first magnetic field gradient; b) determining a second magnetic field gradient; c) determining a ratio of the first and second magnetic field gradient; d) converting the ratio into a position; while matching signal paths of the magnetic sensor elements so as to improve signal-to-noise.
