Abstract
This disclosure is directed to techniques for magnetic field angular position sensing. A device designed in accordance with this disclosure may include a magnetoresistive sensor configured to generate a signal indicative of an angular position of a magnetic field, the signal having an angular range of 180 degrees, a first polarity sensor configured to generate a signal indicative of a polarity of the magnetic field sensed from a first location, and a second polarity sensor configured to generate a signal indicative of a polarity of the magnetic field sensed from a second location different from the first location.
