Abstract
A successive approximation register analog-to-digital converter including a first capacitor group, a second capacitor group and a control circuit is provided. Each of the first and second capacitor groups includes a plurality of capacitors coupled to a common node. In a sampling mode, the control circuit provides an analog signal to the first capacitor group and provides a first voltage to the common node and the second capacitor group. In a sampling mode, the control circuit stops providing the first voltage to the common node and provides a second voltage to the second capacitor group. In a data converting mode, the control circuit reads voltage values of the capacitors of the first capacitor group in sequence. Each when the voltage of at least one specific capacitor in the first capacitor group is read, one capacitor of the second capacitor group is electrically floated.
