摘要： Magnetic field sensors have a magnetic field sensing element and also a feedback circuit to provide a gain-adjustment signal to affect a sensitivity associated with the magnetic field sensing element. In some arrangements, the feedback circuit can include piezoresistors to sense a strain of a substrate over which the magnetic field sensor is disposed. With these arrangements, the feedback circuit can generate the gain-adjustment signal in accordance with the sensed strain. In other arrangements, the feedback circuit can generate pulsed magnetic fields proximate to the magnetic field sensing element in order to directly measure the sensitivity of the magnetic field sensing element. With these arrangements, the feedback circuit can generate the gain-adjustment signal in accordance with the sensed sensitivity.

摘要： 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.
