Abstract:
1. A level shifter, configured to generate an adjusted output signal, comprising: a signal receiving module, comprising at least one signal receiving end for receiving at least one input signal and being conducted or non-conducted according to the input signal; a level adjusting module, comprising a first connection end and a second connection end coupled to the signal receiving module, and configured to generate the adjusted output signal according to the input signal; and a switch module, comprising a first end coupled to the first connection end, a second end coupled to the second connection end and a third end coupled to the input signal, wherein if the switch module is conducted, a current path is formed between the first connection end, the second connection end and the signal receiving module through the switch module, and if the switch module is not conducted, current is blocked from flowing from the first connection end to the second connection end; wherein the switch module is controlled by the input signal.
