Analog switch circuit and sample-and-hold circuit including the same

摘要

First and second analog switches are connected in series between first and second nodes. One terminal of a third analog switch is connected to a series connection node of the first and second analog switches. The other terminal of the third analog switch is supplied with a second voltage different from a first voltage applied to the first node. The third analog switch drives on when the first and second analog switches drive off, and outputs the second voltage to the series connection node of the first and second analog switches.
