ABSTRACT:
A sample-and-hold circuit includes a first switch element which is opened or closed in accordance with a first control signal so as to selectively connect an input signal terminal for receiving an input signal to an internal terminal, a non-linear element for connecting the internal terminal to an output terminal, a potential holding circuit connected between the output terminal and ground, and a second switch element or a current source circuit which is controlled by a second control signal so as to selectively connect the output terminal to ground.
