Classification: CPC H | IPC H

Claim 25:
26. The analog-to-digital conversion circuit according to claim 25, wherein
for the (U+v)-th analog-to-digital conversion of the i-th conversion cycle, the positive shared conversion unit outputs the (U+v)-th positive second analog signal based on the positive quantized margin signal and the v-th positive second control signal, wherein 1≤v≤V and v is an integer,
the negative shared conversion unit outputs the (U+v)-th negative second analog signal based on the negative quantized margin signal and the v-th negative second control signal,
the comparator compares the (U+v)-th positive second analog signal with the (U+v)-th negative second analog signal to output a second comparison signal of the (U+v)-th comparison,
based on v<V, the control module outputs a (v+1)-th positive second control signal and a (v+1)-th negative second control signal based on the second comparison signal of the (U+v)-th comparison, and
based on v=V, the control module outputs the second digital signal corresponding to the first analog signal of the i-th channel based on the second comparison signal of the (U+v)-th comparison.
