Abstract
Methods and apparatus for a magnetic field sensor having a first set of MR elements configured to change in resistance due to an applied magnetic field having an orientation in a sensitive axis of the first set of MR elements and a second set of MR elements that are immune to the applied magnetic field. The second set of MR elements is configured to change in resistance due to temperature. A processor can compensate for the response of the first set of MR elements based on the temperature information from the second set of MR elements.
