Sample-and-hold circuit device.

摘要

A sample-and-hold circuit includes a first switch element (55) 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 (56) for connecting the internal terminal to an output terminal, a potential holding circuit (57) connected between the output terminal and ground, and a second switch element (58) or a current source circuit which is controlled by a second control signal so as to selectively connect the output terminal to ground. <IMAGE>
