Abstract:
An electronic circuit includes a magnetoresistance element for providing an output signal proportional to a magnetic field. The magnetoresistance element also has a hysteresis characteristic. The electronic circuit also includes at least one of a reset conductor or a bias conductor disposed proximate to the magnetoresistance element. For embodiments having a reset conductor, the electronic circuit is configured to generate a reset current carried by the reset conductor in response to the comparison. In response to the reset current, the reset conductor is configured to generate a reset magnetic field at the magnetoresistance element to temporarily force the magnetoresistance element to a saturation region of the hysteresis characteristic.
