Abstract
An analog-to-digital converter with delta-sigma modulation and the modulation unit thereof are disclosed, wherein, for each modulation unit, a pair of input capacitors, a pair of integration capacitors and a differential feedback are operated in a swapping manner for the positive path and the negative path, such that circuit mismatch problems are effectively removed.
