Claim 12:
13. The analog-to-digital conversion circuit according to claim 12, wherein the control module outputting the (v+1)-th second control signal based on the first comparison signal of the (U+v)-th comparison comprises:
in response to the first comparison signal of the (U+v)-th comparison being 1, outputting the (v+1)-th second control signal, so that the other terminal of the (v+1)-th first shared capacitor in the shared conversion module is connected to the ground GND in the (U+v+1)-th analog-to-digital conversion, and
in response to the first comparison signal of the (U+v)-th comparison being 0, outputting the (v+1)-th second control signal, so that the other terminal of the (v+1)-th first shared capacitor in the shared conversion module is connected to the device voltage VDD in the (U+v+1)-th analog-to-digital conversion.
