Disclosed is a sample and hold circuit including a differential circuit, an amplifier stage and a sampling voltage supply circuit. The differential circuit includes first and second capacitance elements, electric charge of which is distributed by a first switch, a first MOS transistor having a gate connected via a second switch to one end of the first capacitance element and also connected via a third switch to an output terminal, and having a source connected to a first current source, a second MOS transistor having a gate connected to one end of the second capacitance element and having a source connected to a second current source and also connected via a forth switch to the source of the first MOS transistor, and a load circuit connected between the drains of the first and second MOS transistors and a terminal of a second power supply. The amplifier stage receives an output of the differential circuit and has an output connected to the output terminal. The sampling voltage supply circuit delivers a sampling voltage to the one end of at least one of the first and second capacitance elements.
