A sampling switch circuit, operating in a maintaining mode or a sampling mode, comprising:
- a switch, comprising a first terminal for receiving an input voltage, and having a control terminal;
- a capacitor, comprising a first terminal and a second terminal;
- wherein the switch is non-conductive when the sampling switch circuit operates in the maintaining mode, where the first terminal of the capacitor receives a predetermined voltage, and the second terminal of the capacitor is coupled to the control terminal when the sampling switch circuit operates in the sampling mode.
A switch capacitor circuit, comprising:
- a plurality of switches;
- a switching module;
