Temperature compensation for magnetic field sensing devices and a magnetic field sensing device using the same

A magnetic field sensing apparatus, comprising:

• a set of magnetic sensors arranged along a sensing path, each magnetic sensor is adapted to sense a magnetic field created by a magnetic actuator and to output a sensing signal indicative of a position and/or a displacement of the magnetic actuator relative to the sensing path;
• and
• a processor adapted to perform signal processing of the sensing signals for determining the position and/or the displacement of the magnetic actuator, the signal processing including:
• selecting one or more magnetic sensors from the set of magnetic sensors for use as temperature sensors;
• estimating a distribution of temperature over at least a portion of the sensing path based on the sensing signals output by the selected one or more magnetic sensors;
• and
• compensating for an effect of temperature on the sensing signals output by one or more magnetic sensors of the set of magnetic sensors using the estimated temperature distribution.
