    Abstract: A method for compensation of dynamic error signals of a chopped Hall sensor that comprises at least one Hall sensor element comprising a plurality of terminal pairs for impressing an excitation current through the Hall sensor element and for taking a Hall voltage. The terminal pairs for impressing the excitation current and for taking the Hall voltage are switched in a first and/or second rotational sense. In order to compensate dynamic error signals caused by the switching, the Hall voltages taken at the terminal pairs when switching in the first rotational sense are supplied to a summation and/or averaging analysis unit together with the Hall voltages taken at the terminal pairs when switching in the second rotational sense.

    Abstract: A modulator (MOD1) is connected to input- and output amplifier stages (V2, V1), all in series. The modulator chops the signal into first and second inverted phases. Miller compensation capacities (C1, C2) are connected in alternation between the output and input of the output amplifier stage (V1), in phase with the chopping cycle. An independent claim is included for the corresponding method of operation.

    Abstract: A signal conditioning arrangement includes a sensor arrangement for sensing a measured quantity and for outputting an output signal having a first or a second logical signal state based on the measured quantity, and means for generating an evaluating impulse if the logical signal state of the output signal does not change for a maximum predetermined time duration, and which are further formed to allocate a first or a second pulse signal state, which differs from the signal state of the output signal which the output signal has during the predefined time duration, to the evaluating impulse. Furthermore, the signal conditioning arrangement includes means for combining the output signal and the evaluating impulse, with means for providing being formed to provide a conditioned output signal, the conditioned output signal having, when an evaluating impulse is present, the impulse signal state thereof and otherwise having the logical signal state of the output signal.

    Abstract: A circuit configuration for processing a signal of a sensor includes an amplifier for amplifying the signal of the sensor. This signal has switch-over points between different signal states. The circuit configuration is constructed in such a manner that the amplifier and the sensor operate continuously in a chopper mode. Furthermore, a control loop is provided for determining offset components in the signal of the sensor and for removing the offset components from the signal of the sensor.

    Abstract: Die vorliegende Offenbarung betrifft Chopper-Verstärkerschaltungen mit inhärenter Chopper-Welligkeitsunterdrückung. Ausführungsbeispiele können eine doppelt genutzte Chopper-Verstärkerschaltung als stromsparende Schaltung mit einer Wake-up-Funktion realisieren, die in der Lage ist, ein Self-Awake-Signal bereitzustellen, um in einen schnellen, jitterarmen / latenzarmen Modus zu wechseln und bei Signaländerungen ein Wake-up-Signal für einen schlafenden Mikroprozessor oder ein System bereitzustellen
