Magnetic position sensor system, device and method

A method of determining a position of a sensor device,

• wherein the sensor device is movable relative to a magnetic source with 1 or 3 mechanical degrees of freedom, or vice versa;
• the sensor device comprising a semiconductor substrate comprising a plurality of at least two magnetic sensors situated in at least two different locations;
• the method comprising the steps of:
• a) obtaining a plurality of sensor signals from said plurality of magnetic sensors;
• b) determining the position of the sensor device relative to the magnetic source based on said plurality of magnetic sensor signals and/or signals derived therefrom;
• wherein
• step b) comprises determining said position using an artificial neural network;
• wherein the artificial neural network is a recurrent neural network having a predefined number of trainable parameters, which are trained for determining said position;
• and
• wherein the number of trainable parameters is at most 300 per mechanical degree of freedom.
