Abstract
A magnetic sensing method and system include a die comprising a central location thereof. A group of magnetoresistive bridge circuits are located and configured upon the die. A magnetic biasing component is then utilized to bias the plurality of magnetoresistive bridge circuits with a magnetic field rotating about an axis of the central location of the die in order to generate a plurality of bridge output signals thereof. Finally, the plurality of bridge output signals are processed in order to determine position data thereof.
