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.

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.
