Abstract: The current disclosure relates to an angular sensor. The angular sensor includes a sensing module, a digital processor and an incremental interface. The sensing module is configured to generate a sensing signal containing measurements of rotation activities of a rotating physical entity. The digital processor is configured to process and store the sensing signal. The incremental interface is coupled to the digital processor and includes an incremental pulse generator and a status data encoder. The incremental pulse generator is configured to convert and transmit the sensing signal as incremental square pulses through a unidirectional signal line, which are processed to generate rotary angle and direction of the physical entity. The status data encoder is configured to convert and transmit the sensing signal as a reference pulse and a status signal through a bidirectional signal line, which can be to request an absolute angle position or other sensor data.

Abstract: A vertical Hall sensor circuit comprises an arrangement comprising a vertical Hall effect region of a first doping type, formed within a semiconductor substrate and having a stress dependency with respect to a Hall effect-related electrical characteristic. The vertical Hall sensor circuit further comprises a stress compensation circuit which comprises at least one of a lateral resistor arrangement and a vertical resistor arrangement. The lateral resistor arrangement has a first resistive element and a second resistive element, which are parallel to a surface of the semiconductor substrate and orthogonal to each other, for generating a stress-dependent lateral resistor arrangement signal on the basis of a reference signal inputted to the stress compensation circuit. The vertical resistor arrangement has a third resistive element of the first doping type for vertically conducting an electric current flow, for generating a stress-dependent vertical resistor arrangement signal on the basis of the reference signal. The vertical Hall sensor circuit further comprises a first circuit for providing a first signal to the arrangement, the first signal being based on at least one of the stress-dependent lateral resistor arrangement signal and the stress-dependent vertical resistor arrangement signal.

Abstract: 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. The offset error can be reduced using a correction factor based on a first offset error of the sensor system when operated in a first phase and a second offset error of the sensor system when operated in second first phase. The sensor system can generate an output signal based on first and second output signals generated when operating in the first and second phases, respectively.

Abstract: Embodiments relate to systems and methods for self-diagnostics and/or error detection using multiple signal paths in sensor and other systems. In an embodiment, a sensor system comprises at least two sensors, such as magnetic field sensors, and separate signal paths associated with each of the sensors. A first signal path can be coupled to a first sensor and a first digital signal processor (DSP), and a second signal path can be coupled to a second sensor and a second DSP. A signal from the first DSP can be compared with a signal from the second DSP, either on-chip or off, to detect faults, errors, or other information related to the operation of the sensor system. Embodiments of these systems and/or methods can be configured to meet or exceed relevant safety or other industry standards, such as safety integrity level (SIL) standards.
