Abstract / Hauptanspruch
The present invention relates to a position sensing device for measuring a position, comprising a position sensing device for measuring a position, comprising
- a plurality of sensors (2) arranged to produce sense signals each being a function of an input phase (θ i) representative of a position to be measured,
-a combiner circuit (4) arranged to generate an error signal (5) by combining said sense signals according to an array of weight factors,
- a processing block (6) arranged for filtering said error signal and for outputting a phase value representative of said position,
- a feedback loop comprising a feedback signal unit (8) arranged for receiving said output phase value and for adjusting based on said received output phase value said array of weight factors.
