    Abstract: An analog-to-digital converter includes a digital-to-analog converter comprising a capacitor divider network comprising a plurality of dividing capacitors and a dummy capacitor. The digital-to-analog converter is configured to selectively apply an input voltage and a reference voltage to the dividing capacitors and to selectively apply the input voltage and a shift voltage to the dummy capacitor. The analog-to-digital converter further includes a comparison circuit configured to compare an output of the capacitor divider network and a common mode voltage and a shift voltage generator circuit configured to generate the shift voltage. The shift voltage generator circuit may be configured to vary the shift voltage for different samples of the input voltage. For example, the shift voltage generator circuit may be configured to change the shift voltage for succeeding samples by an amount corresponding to 1/(2^M) times the reference voltage to support 2^M oversampling of the input voltage.
