Abstract
For automatic initialization of a level shifter, an input signal in respect of a first voltage source is converted into a substantially zero voltage signal in response to an initial voltage derived from voltages of a first voltage source and a second voltage source when the second voltage source is activated but the first voltage source has not been activated yet. Afterwards, when the first voltage source and the second voltage source are both activated, the input signal in respect of the first voltage source is shifted into the output signal in respect the second voltage source without cooperation of the initial voltage.
