摘要： Embodiments relate to stress compensation in differential sensors. In an embodiment, instead of compensating for stress on each sensor element independently, stress compensation circuitry aims to remove stress-related mismatch between two sensor elements using the sensor elements themselves to detect the mismatch. A circuit can be implemented in embodiments to detect mechanical stress-related mismatch between sensor elements using the sensor elements, and tune the output signal by a compensation factor to eliminate the mismatch. Embodiments are therefore less complicated and less expensive than conventional approaches. While embodiments have applicability to virtually any differential sensor, including magnetic field, pressure, temperature, current and speed, an example embodiment discussed herein relates to magnetic field.
摘要翻译：实施例涉及差动传感器中的应力补偿。在一个实施例中，代替独立地补偿每个传感器元件上的应力，应力补偿电路旨在消除使用传感器元件本身的两个传感器元件之间的应力相关失配，以检测失配。在实施例中可以实现电路以使用传感器元件检测传感器元件之间的机械应力相关失配，并且通过补偿因子来调整输出信号以消除不匹配。因此，实施例比常规方法更不复杂和便宜。虽然实施例可适用于几乎任何包括磁场，压力，温度，电流和速度的差分传感器，但本文讨论的示例实施例涉及磁场。

摘要： One embodiment of the present invention relates to a magnetic field sensor comprising a squat soft-magnetic body disposed on a surface of a substrate comprising a magnetic sensor array having a plurality of spatially diverse magnetic sensor elements disposed in a predetermined configuration. In the presence of an external magnetic field the squat soft-magnetic body becomes magnetized to generate a reactionary magnetic field. The plurality of magnetic sensor elements are respectively configured to measure a magnetic field value of a superposition of the external magnetic field and the reactionary magnetic field along a first axis (e.g., a z-axis), resulting in a plurality of spatially diverse measurements of the magnetic field component along the first axis. The plurality of spatially diverse measurements may be used to compute magnetic field components of the external magnetic field along a plurality of axes (e.g., x-axis, y-axis, and z-axis).

摘要： Embodiments relate to magnetoresistive (xMR) sensors which provide a yaw angle between a reference premagnetization direction of the sensor layer and the magnetic field to be detected, or between a direction of a bias magnetic field and the magnetic field to be detected. In an embodiment, an xMR sensor is rotated or tilted with respect to a direction of a magnetic field to be sensed such that a premagnetization direction of the reference premagnetization layer of the xMR sensor is also rotated or tilted at some yaw angle with respect to the direction of the magnetic field. In another embodiment, a bias magnet or other source is used with sensors not having premagnetization or reference layers, such as anisotropic magnetoresistive (AMR) sensors, and the direction of the bias magnetic field is also tilted or rotated with respect to the direction of the magnetic field to be detected.
