PROBLEM TO BE SOLVED: To suppress a high frequency component of an input signal without hindering miniaturization of an electronic component.SOLUTION: A sampling circuit comprises sampling capacitors 105A_1, 105A_2 and 105B_1, 105B_2 for storing charges generated by an incoming input signal, and includes a plurality of switches 101A_1, 101A_2, 101B_1, 101B_2, 102A_1, 102A_2, 102B_1, 102B_2, 103A_1, 103A_2, 103B_1, 103B_2, 104A_1, 104A_2, 104B_1, 104B_2 for storing charges in the respective sampling capacitors. A circuit including the sampling capacitors 105A_1, 105A_2 and a circuit including 105B_1, 105B_2 are alternately operated, and the two circuits including the sampling capacitors alternately store the charges and alternately transfer the charges. |
