Abstract: A programmable transducer device that includes a signal source (e.g., a sensor) and a transducer output to output a transducer output signal and to receive a control signal from an external control unit. The control signal is superposed on the transducer output signal, and is detected at the transducer output from a resultant superposition signal by a detector circuit. The transducer output signal and the control signal may co-exist on the transducer output. Advantageously, providing a programmable transducer device that is actuated by control signals conducted through the transducer output and does not need to be switched over to a special receiving state, ensures the uninterrupted transmission of transducer output signals even while the control signals are received by the programmable transducer device. In addition, no additional signal path is required for programming.

Abstract: To detect a fault state due to a line break in power supply lines on the receiving side during the operation of a transducer device, the transducer output voltage is forced to an extreme voltage range by a co-integrated p-channel-depletion-transistor. As a result, the signal detection device can reliably detect the presence of the fault state due to a line break in the supply feed lines.

Abstract: The invention relates to a magnetic-field sensor with a Hall effect device, a power supply, and an evaluating facility, which can be supplied with a Hall signal from the Hall-effect device and comprises an input amplifier, a storage element, and a signal superposition unit. To improve the accuracy of the magnetic-field sensor, in a first phase, a balancing signal for balancing the measurement-signal path with respect to an interface can be produced with the evaluating facility, the balancing signal being storable in the storage element, and in a second phase, the balancing signal stored in the storage element can be applied through the signal superposition unit to the interface, where it is superimposed on a Hall signal.

Abstract: 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.

Abstract: 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.
