ABSTRACT:
A sampling switch is the one for sampling an input voltage and providing an output voltage, comprising a MOS transistor for being supplied by the input voltage to the source terminal thereof and providing the output voltage from the drain terminal thereof; and a gate voltage control unit for supplying a voltage to the gate terminal of the MOS transistor with a delayed time from the input voltage. This enables a change in the on-resistance of a MOS transistor used for a sampling switch to be suppressed to a minimum, thereby reducing a distortion of signals induced by a change in the on-resistance.
