Abstract:
An analog-to-digital converter includes a comparison unit that outputs a result obtained by comparing a voltage of an input node with a comparison voltage; 1st to Nth capacitors having one ends connected to the input node, respectively; and 1st to N−1th voltage selection units corresponds to the 2nd to Nth capacitors, respectively and applies one of a voltages of a 1st node, a 2nd node, and the comparison voltage to the other ends of the corresponding capacitors. An input signal is sampled to the input node, the 1st to N−1th voltage selection units select one of the voltages of the 2 nodes and convert a part of the input signal into a 1st digital signal, and the 1st to N−1th voltage selection units select one of the voltages of the 2 nodes and convert the remaining part of the input signal into a 2nd digital signal.
