Classification: CPC H | IPC H

Claim 7:
8. The analog-to-digital conversion circuit according to claim 5, wherein the control module outputting the (u+1)-th first control signal based on the first comparison signal of the u-th comparison comprises:
in response to the first comparison signal of the u-th comparison being 1, outputting the (u+1)-th first control signal to connect the other terminal of the (u+1)-th first sampling capacitor in the i-th sampling and conversion module to the ground GND in the (u+1)-th analog-to-digital conversion, and
in response to the first comparison signal of the u-th comparison being 0, outputting the (u+1)-th first control signal to connect the other terminal of the (u+1)-th first sampling capacitor in the i-th sampling and conversion module to the device voltage VDD in the (u+1)-th analog-to-digital conversion.
