摘要： One embodiment of the present invention relates to a method and apparatus for removing the effect of contact resistances for Hall effect device contacts. In one embodiment, the apparatus comprises a Hall effect device comprising a plurality of force and sense contact pairs. The force and sense contact pairs comprise a force contact and a separate and distinct sense contact. The force contact is configured to act as a supply terminal that receive an input signal while the sense contact is configured act as an output terminal to provide an output signal indicative of a measured magnetic field value. By utilizing separate contacts for inputting a signal (e.g., an applied current) and reading out a signal (e.g., an induced voltage) the non-linearities generated by contact resistances may be removed, thereby minimizing the zero point offset voltage of the measured magnetic field.

摘要： Embodiments relate to multi-contact sensor devices and operating methods thereof that can reduce or eliminate offset error. In embodiments, sensor devices can comprise three or more contacts, and multiple sensor devices can be combined. The sensor devices can comprise Hall sensor devices, such as vertical Hall devices, or other sensor types.

In a first operating mode, the sensor is supplied with the same input current in all operating phases, with the output voltages of all operating cycles sensed and processed. In another operating mode, the sensor device is supplied with the same input voltage in all operating phases, the sense terminals are forced to constant potentials, and the currents flowing into or out of the sense terminals are sensed and processed.

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.
