Abstract

See full text

An incremental analog-to-digital converter including a first-stage non-delay memorization element and other elements is disclosed. An ending time point of a second reset signal received by the first-stage non-delay memorization element is later than an ending time point of a first reset signal received by the other elements by at least one clock cycle, a reset duration of the first-stage non-delay memorization element is longer than a reset duration of the other element, so that the first-stage non-delay memorization element can be prevented from occurring overshoot or spike on an output thereof, and the incremental analog-to-digital converter can maintain a good signal-to-noise and distortion ratio under the condition that the internal elements has low swing limits.
