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: Various embodiments discussed herein can comprises systems or methods that can improve over existing spinning current Hall sensor systems via at least one of interleaving spinning phases or sliding averaging/summing. One example embodiment can comprise a sensor system comprising M (a positive integer) spinning current Hall sensors, each of which has N (an integer greater than one) distinct spinning phases during which it can acquire sensor data, and a multiplexer that can select sensor data of the sensors according to a M×N spinning phase sensor sequence. The M×N distinct spinning phases of the sensor sequence can be interleaved, wherein the average in the time domain of the N spinning phases for each sensor is the same. For each of the M sensors, a sum and/or an average can be determined for one or more most recent representations of sensor data from that sensor.

Abstract: A device may determine a sensor identifier corresponding to a sensor integrated circuit (IC) associated with a sensor system. The device may provide the sensor identifier corresponding to the sensor IC. The device may receive, based on providing the sensor identifier, compensation parameter information associated with the sensor IC. The device may cause a set of compensation parameters, associated with the compensation parameter information, to be stored on a controller associated with the sensor system. The set of compensation parameters may include one or more parameters associated with correcting a measurement performed by the sensor IC or a safety result provided by the sensor IC.

Abstract: Stress compensated systems and methods of compensating for electrical and mechanical stress are discussed. One example system can include a first circuit and a global stress compensation component. The first circuit can be configured to generate a first signal and can comprise at least one local stress compensation component (e.g., employing dynamic element matching, chopping, etc.). The global stress compensation component can comprise one or more stress sensors configured to sense one or more stress components associated with the system. The global stress compensation component can be configured to receive the first signal and to compensate for stress effects on the first signal.

Abstract: A sensor system for detecting a characteristic of a target object is described. The sensor system can include a sensor, such as a magnetic sensor, configured to sense magnet field components and to generate corresponding magnet field component signals based on the sensed magnet field components. The sensor system can include a processor that is configured to calculate a magnetic field angle based third magnetic field components. For example, the magnetic field angle can be calculated by determining a quadratic sum of a plurality of the magnetic field components. The characteristic of the target object can be determined based on the calculated magnetic field angle.

Abstract: A ΣΔ ADC includes a forward path, a feedback path, and offset compensation circuitry. The forward path is configured to convert an analog input signal to a digital output signal and includes analog chopper circuitry configured to shift the analog input signal to a chopper frequency to generate a chopped analog signal. The feedback path includes a ΣΔ DAC configured to convert a digital offset compensation signal configured to compensate for offset error in the analog input signal to an analog feedback signal that is subtracted from a forward path signal. The offset compensation circuitry is configured to accumulate a chopped digital signal from the forward path to generate a digital offset error signal; add the digital offset error signal to the digital output signal to generate the digital offset compensation signal; and provide the digital offset compensation signal to the ΣΔ DAC.

Abstract: Embodiments relate to magnetic field angle sensing systems and methods. In an embodiment, a magnetic field angle sensing system configured to determine a rotational position of a magnetic field source around an axis, comprises N sensor devices arranged in a circle concentric to an axis, wherein N>1 and the sensor devices are spaced apart from one another by about (360/N) degrees along the circle, each sensor device comprising a magnetic field sensing device having a sensitivity plane comprising at least one reference direction of the magnetic field sensing device, wherein the magnetic field sensing device is sensitive to a magnetic field component in the sensitivity plane and configured to provide a signal related to a (co)sine of an angle between the reference direction and the magnetic field in the sensitivity plane; and circuitry coupled to the N sensor devices and configured to provide a signal indicative of a rotational position of a magnetic field source around the axis determined by combining the signals from the magnetic field sensing devices of the N sensor devices, wherein the circuitry is configured to (i) interpret the signal of the N sensor devices as angle values, (ii) add integer multiples equivalent to 360° to selective ones of the N angle values to result in at least one monotonously rising or falling sequence of all N corrected values in a single clockwise or counter-clockwise direction of angular positions of respective ones of the N sensor devices, and (iii) average these corrected values.
