    Abstract: A multi-bit sigma/delta converter for converting an analog input signal into a digital output signal comprises a filter device for filtering the analog input signal which is added to a feedback signal to form an intermediate signal. An integrator device for integrating the filtered intermediate signal added to an inner feedback signal forms a quantizer input signal. A quantizer device quantizes the quantizer input signal to form the digital output signal. An inner feedback digital/analog converter is provided for converting the digital output signal directly into the inner feedback signal. A DEM device for performing dynamic element matching on the digital output signal and providing a matched digital signal is provided and a feedback digital/analog converter for converting the matched digital signal into the feedback signal is implemented.

    Abstract: Described is a magnetic field sensor with a Hall element and a rectangular change-over switch, which controls the Hall element, dependent upon a timing signal. An active ladder-type filter creates a low pass filtered outlet signal. It uses OTA modules, which work with gyrator switching. By means of a chopper operation, capacitors, dependent on the timing signal, are charged alternately from the outlets of the OTA modules.

    Abstract: Embodiments relate to stress sensors and methods of sensing stress. In an embodiment, a stress sensor comprises a vertical resistor. The vertical resistor can comprise, for example, an n-type resistor and can have various operating modes. The various operating modes can depend on a coupling configuration of terminals of the resistor and can provide varying piezo-coefficients with very similar temperature coefficients of resistances. Comparisons of resistances and piezo-coefficients in differing operating modes can provide a measure of mechanical stresses acting on the device.

    Abstract: The present disclosure relate to a sensor system having a low offset error. In some embodiments, the sensor system comprises a sensor configured to generate a sensor signal, which is provided to a main signal path having a first chopping correction circuit and a second chopping correction circuit. The first and second chopping correction circuit chop the sensor signal at first and second frequencies to reduce offset errors, but in doing so generate first and second chopping ripple errors. A first digital offset feedback loop generates a first compensation signal, which is fed back into the main signal path to mitigate the first chopping ripple error. A second digital offset feedback loop generates a second compensation signal, which is fed back into the main signal path to mitigate the second chopping ripple error.

    Abstract: One embodiment of the present invention relates to a magnetic sensor circuit having a magnetic field sensor device configured to generate a digital signal proportional to an applied magnetic field. An analog-to-digital converter converts the analog signal to a digital signal that is provided to a digital signal processing unit, which is configured to digitally track the analog output signal.
