  • Switched capacitor circuit and compensation method thereof, and analog to digital converter
    Patent number: 9413377
    Abstract: A switched capacitor circuit with feedback compensation is provided. First terminals of a feedback capacitor and at least one capacitor are coupled to a first input terminal of a differential amplifier. Second terminals of the feedback capacitor and the capacitor are coupled to an input terminal during a first period. A feedback compensation circuit amplifies a first voltage on the first input terminal of the differential amplifier by a gain greater than one to generate a second voltage. The second terminal of the feedback capacitor is coupled to the output terminal of the differential amplifier, and the feedback compensation circuit applies the second voltage to the second terminal of the capacitor during a second period.
