Claim 0:
1. A multiplexer, comprising:
a charging circuit including a first charging switch connected to a first power node for outputting a first power voltage, a second charging switch connected to a second power node for outputting a second power voltage lower than the first power voltage, and a capacitor connected between a first node connected to the first charging switch and a second node connected to the second charging switch;
a plurality of sampling switches configured to receive a plurality of input signals; and
a plurality of boosting circuits connected between the plurality of sampling switches and the charging circuit and configured to share the charging circuit,
wherein the first charging switch and the second charging switch are controlled by a first clock signal, and
wherein each of the plurality of boosting circuits includes a first boosting switch connected to the first node and a gate of one of the plurality of sampling switches, a second boosting switch connected between the second node and the one of the plurality of sampling switches, and a level shifter configured to control the first boosting switch and the second boosting switch in response to a second clock signal and a selection signal,
wherein the level shifter includes pull-up devices connected to the first power node, pull-down devices connected to the second power node, and capacitors connected between gates of the pull-up devices and gates of the pull-down devices.
