摘要： Embodiments relate to systems and methods for sensor self-diagnostics using multiple signal paths. In an embodiment, the sensors are magnetic field sensors, and the systems and/or methods are configured to meet or exceed relevant safety or other industry standards, such as SIL standards. For example, a monolithic integrated circuit sensor system implemented on a single semiconductor ship can include a first sensor device having a first signal path for a first sensor signal on a semiconductor chip; and a second sensor device having a second signal path for a second sensor signal on the semiconductor chip, the second signal path distinct from the first signal path, wherein a comparison of the first signal path signal and the second signal path signal provides a sensor system self-test.

摘要： Some aspects of the present disclosure provide for a sensor system having a large range between minimum and maximum allowed input quantities. In some embodiments, the sensor system has a nonlinear sensor and a linear sensor. The nonlinear sensor is generates a first nonlinear signal corresponding to a detected physical input quantity. The linear sensor generates a second linear signal corresponding to the detected physical input quantity. A signal processor receives the first nonlinear signal and the second linear signal and generates a composite output signal that corresponds to the detected physical input quantity. The composite output signal is a combination of the first nonlinear signal and the second linear signal that provides for a signal having a high sensitivity to small physical input quantities while avoiding saturation at large physical input quantities.

摘要： Embodiments relate to reducing offset error in sensor systems. In embodiments, the sensitivity and offset of a sensor depend differently on some parameter, e.g. voltage, such that operating the sensor at two different values of the parameter can cancel the offset error. Embodiments can have applicability to stress sensors, Hall plates, vertical Hall devices, magnetoresistive sensors and others.

摘要： Embodiments relate to stress sensors and methods of sensing stress. In an embodiment, a stress sensor comprises a vertical resistor. The vertical resistor can comprise, for example, an n-type resistor and can have various operating modes. The various operating modes can depend on a coupling configuration of terminals of the resistor and can provide varying piezo-coefficients with very similar temperature coefficients of resistances. Comparisons of resistances and piezo-coefficients in differing operating modes can provide a measure of mechanical stresses acting on the device.
