摘要： A sensor circuit is configured and operated in the presence of interference. In connection with various example embodiments, a stray magnetic field is sensed with current sensors that also respectively sense current-induced magnetic fields generated by current flowing in opposing directions through different portions of a conductor. The current-induced magnetic fields and the stray magnetic field are coplanar, and the current sensors are arranged such that a portion of the output from each current sensor corresponding to the stray magnetic field is canceled when the sensor outputs are combined.

摘要： An AMR sensor, comprises at least first and second AMR sensor elements to which opposite bias fields are applied. The first and second AMR sensor element outputs are combined to derive a sensor response which is substantially anti-symmetric in the region close to zero external magnetic field. This arrangement shifts the zero detection point of the AMR sensor elements away from a maximum of the response curve, so that sensitivity in proximity to a zero input field is obtained. To overcome the problem that the response is not anti-symmetric, the signals from (at least) two sensor elements are combined.
