ABSTRACT:
A pipeline analog-to-digital converter including: a first conversion module, a second conversion module, at least a comparator, a first switch module and a second switch module. The first conversion module includes a first storage unit and a first multiplying digital-to-analog converter (MDAC). An input end of the second conversion module is coupled in series with an output end of the first conversion module. The second conversion module includes a second storage unit and a second MDAC. The first switch module is utilized for coupling the input end of the first conversion module or the second conversion module to an input end of the comparator; and the second switch module is utilized for coupling an output end of the comparator to the first or the second storage unit.
