Claim 7:
8. A magnetic position sensor device comprising a semiconductor substrate comprising:
at least a first magnetic sensor located at a first sensor location, and a second magnetic sensor located at a second sensor location, spaced apart from the first sensor location;
at least a first biasing source for biasing the first magnetic sensor, and a second biasing source for biasing the second magnetic sensor;
at least a first amplifier for amplifying a signal obtained from the first magnetic sensor, and a second amplifier for amplifying a signal obtained from the second magnetic sensor;
at least a third magnetic sensor, and optionally a fourth magnetic sensor;
at least a third biasing source for biasing the third magnetic sensor, and optionally a fourth biasing source for biasing the fourth magnetic sensor;
at least a third amplifier for amplifying a signal obtained from the third magnetic sensor, and optionally a fourth amplifier for amplifying a signal obtained from the fourth magnetic sensor;
a temperature sensor located at a predefined position on the substrate;
at least one differential stress sensing circuit configured for determining at least one stress difference between two of said magnetic sensors;
at least one analog-to-digital-converter connected downstream of said amplifiers;
a digital processing circuit connected downstream of the analog-to-digital-converter;
a non-volatile memory operatively connected to the digital processing circuit, configured for storing one or more values or parameters of said predefined function;
wherein the digital processing circuit is configured for performing a method according to claim 1.
