PROBLEM TO BE SOLVED: To provide a sample-hold circuit 100 that is used for performing a sample and hold function. SOLUTION: The circuit 100 includes a switch 112 provided with a current path coupled between an input node VIN and an output node VOUT. A capacitor 114 is coupled with the output node VOUT. A replica device 160 includes a current path coupled between the input node VIN and a supplied voltage node VDD. For example, a bootstrap circuit including a component such as a bootstrap capacitor 164 is coupled between a control terminal of the 1st switch 112 and a control terminal of the replica device 160. |
