Abstract:
An exemplary embodiment of such a system includes: a level shifter operative to transform an input signal into an output signal, the level shifter includes: a voltage distributor operative to receive the input signal and distribute potential levels at a first node and a second node to respectively output a first signal and a second signal, and the voltage distributor includes: a current limiter, operative to provide a limited current passing through the first node; a switch, operative to selectively establish an electrical connection between the first node and the second node; and a first transistor having a first electrode, a second electrode, and a first control electrode, wherein the first electrode is connected to the second node, the second electrode is utilized to receive the input signal, and the first control electrode is coupled to the first node; and an output circuit, operative to generate the output signal.
