Zusammenfassung:	A semiconductor device includes a sample and hold circuit which has an analog switch and a first capacitor and which samples and holds an analog input signal, and a boost circuit which has a boost part which boosts a sampling clock pulse and a clamp part which limits a boosted voltage to a predetermined level. The sample and hold circuit operates a boosted sampling clock pulse. The boost circuit includes a control circuit which operates the clamp part only at the moment the sampling clock pulse changes to a high level.
