Patent ID: 7486103

Claim:
A switching system, comprising: a first switch, for conducting a first signal according to a first control signal; a second switch, for conducting a second signal according to a second control signal; and a driving unit, for receiving a third signal and a fourth signal, wherein the driving unit respectively produces the first control signal and the second control signal according to the third signal and the fourth signal, and the driving unit further comprises: a third switch; a fourth switch, wherein the third switch and the fourth switch are operated between a first voltage and a second voltage, and a voltage level of an output terminal of the third switch is determined by the third signal; a fifth switch; a sixth switch, wherein the fifth switch and the sixth switch are operated between the first voltage and the second voltage, and a voltage level of an output terminal of the fifth switch is determined by the fourth signal; and a first level-adjusting circuit, disposed on a first path, wherein the third switch and the fifth switch are on the first path and the first level-adjusting circuit adjusts input voltage levels of the third switch and the fifth switch, wherein voltages of the first control signal and the second control signal are restricted within a first voltage interval so as to reduce a noise produced during switching of the first and second switches.
