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.

Abstract: An angle sensor device includes first and second magnet tracks, a sensor component, and a control unit. The first and second magnet tracks are fixed to a rotatable object and are configured to generate a non-homogenous field. The rotatable object is configured to rotate about a rotation axis and the non-homogenous field has a smaller gradient of magnitude along a rotational direction than a perpendicular direction, which is perpendicular to the rotational direction. The sensor component is positioned off-axis and is configured to measure a magnetic field including the non-homogenous field and provide magnetic field measurements. The control unit is configured to determine angular information from the magnetic field measurements.

Abstract: Various apparatuses and methods are described where a signal is amplified using a chopper amplifier arrangement, and ripples caused by said chopper amplifier arrangement are reduced. In some cases, this reduction of ripples is performed by controlling a voltage offset of an amplifier of said chopper amplifier arrangement. In other embodiments, a detection of ripples or a chopping of the chopper amplifier arrangement is at least temporarily disabled.

Abstract: One embodiment of the present invention relates to a method and apparatus to perform a low power activation of a system by measuring the slope of a digital signal corresponding to a motion sensor measurement value. In one embodiment, a low power activation circuit is coupled to magnetic motion sensor configured to output a magnetic signal proportional to a measured magnetic field. The low power activation circuit may comprise a digital tracking circuit configured to provide a digital signal that tracks the magnetic field and a difference detector configured to detect a difference between a current digital signal and a prior digital signal stored in a digital storage means. If the detected difference is larger than a digital reference level, an activation signal is output to awaken a system from a sleep mode.

Abstract: A spinning current Hall sensor configured to provide a sequence of input signals in response to a bias current being applied to a sequence of terminals of Hall sensing elements of the Hall sensor, the terminals of the Halls sensing elements configured to be interconnected in a sequence of configurations between a bias current supply and ground, with the bias current supply being connected to and applying the bias current to a different one of the terminals of each configuration. A chopping circuit demodulates the sequence of input signals to provide a corresponding sequence of demodulated positive and negative signals, with a residual offset calibration signal for the spinning current Hall sensor being based on the sequence of demodulated positive and negative signals.

Abstract: A vertical Hall sensor includes first and second vertical Hall effect regions formed in a semiconductor substrate and of the same doping type, with first and second pluralities of contacts arranged at one side of the first or second vertical Hall effect regions, respectively. The second vertical Hall effect region is connected in series with the first vertical Hall effect region regarding a power supply to the first and second vertical Hall effect regions. The vertical Hall sensor further includes first and second layers adjacent to the first and second vertical Hall effect regions at a side other than a side of the first or second pluralities of contacts. The first and second layers have different doping properties than the first and second vertical Hall effect regions and insulate the first and second vertical Hall effect regions from a bulk of the semiconductor substrate by at least one reverse-biased p-n junction per vertical Hall effect region during an operation of the vertical Hall sensor.
