Abstract

See full text

An analog-to-digital converter can include: a charge distribution and holding module configured to sample a to-be-converted signal, and to perform subtraction on the to-be-converted signal and a target reference voltage by charge distribution, in order to generate a positive-phase output voltage and a negative-phase output voltage on a first and second electric rails, respectively; a common-mode voltage compensation module coupled with the first and second electric rails, and being configured to inject common-mode charges to compensate the distributed charges of the charge distribution and holding module, and to reduce a difference between a common-mode output voltage of the charge distribution and holding module and an expected value; and a comparator configured to provide a logic signal based on a comparison between the positive-phase output voltage and the negative-phase output voltage, where the logic signal corresponds to a target digital signal of the analog-to-digital converter.
