ABSTRACT:
A sample-and-hold circuit device capable of realizing a high-precision and high-speed operation, in which the output signal is independent of the error signal caused by a MOS transistor. The circuit includes a first switch coupled between an input terminal and a first internal terminal, a second switch coupled between the first internal terminal and a second internal terminal, a capacitor coupled between the second internal terminal and a reference potential, a buffer for transferring a potential held in the capacitor to an output terminal, a control signal generator for controlling the first switch to turn off after the second switch is turned off, and then to again turn on the second switch so as to replace an error charge into the second switch.
