Abstract: A switch device includes a first node, a switch unit, an adjustment switch, an impedance element, a second node and a detection unit. A first terminal of the switch unit is coupled to the first node. A first terminal and a second terminal of the adjustment switch are respectively coupled to a second terminal of the switch unit and a reference voltage terminal. A first terminal and a second terminal of the impedance element are respectively coupled to the first terminal and the second terminal of the adjustment switch. The detection unit is coupled to the second node, and a control terminal of the switch unit and a control terminal of the adjustment switch. The detection unit detects a node signal at the second node to accordingly control the switch unit and the adjustment switch.
