  • Amplifier circuit arrangement and method to calibrate the same
    Patent number: 10840866
    Abstract: An amplifier circuit arrangement and a method for calibrating the same. In an embodiment an amplifier circuit arrangement includes a desired signal path including a differential amplifier for an analog signal having an input side and an output side and an analog-to-digital converter having an output terminal, a first feedback path to calibrate an offset of the desired signal path coupled to differential signal lines at the output side of the differential amplifier and to differential signal lines at the input side of the differential amplifier, the first feedback path including a comparator and at least one counter controlled by an output of the comparator and a second feedback path to calibrate a drift of the desired signal path coupled to the output terminal of the analog-to-digital converter and to the differential signal lines at the input side of the differential amplifier, the second feedback path including an average filter.
