1. A magnetic sensing method, comprising:

  • providing a die comprising a central location thereof;

    locating a plurality of magnetoresistive bridge circuits upon said die, said plurality of magnetoresistive bridge circuits comprises a rotary AMR array configuration;

    biasing said plurality of magnetoresistive bridge circuits with a magnetic field rotating about an axis of said central location of said die in order to generate a plurality of bridge output signals thereof, wherein said plurality of magnetoresistive bridge circuits are biased utilizing a magnetic biasing component; and

    processing said plurality of bridge output signals in order to determine position data thereof.
