Magnetic Sensor Having Enhanced Linearization By Applied Field Angle Rotation |
| 摘要 |
Method and apparatus for a current sensing device including a magnetoresistive magnetic field sensing element positioned with respect to a shaped conductor such that an applied field generated by current through the shaped conductor forms an offset angle theta defined by the applied field and a field of a pinning layer of the magnetoresistive element. The offset angle increases a linearity of the device output for current in the shaped conductor flowing in a first direction. A further sensor can increase linearity in the opposite direction, |

1. A device, comprising:
a first magnetoresistive magnetic field sensing element positioned with respect to a shaped conductor such that an applied field generated by current through the shaped conductor forms an offset angle theta defined by the applied field and a field of a pinning layer of the first magnetoresistive magnetic field sensing element, wherein the offset angle theta is greater than about five degrees to increase a linearity of an output of the first magnetoresistive magnetic field sensing element for current in the shaped conductor flowing in a first direction; and an output module to receive the linearized signal and provide a device output signal. |
