Patent ID: 7772912

Claim:
A level shift circuit comprises: a first input terminal, for receiving an input signal; a second input terminal, for receiving an inverted input signal which is an inverse of the input signal; a first output terminal, for outputting an output signal; a second output terminal, for outputting an inverted output signal; a level shifter, connected to the first input terminal, the second input terminal, the first output terminal and the second output terminal; a control unit, coupled between a power supply and the level shifter, controlled by an enable signal; and an equalization unit, coupled between the first output terminal and the second output terminal; wherein at a reset phase, the input signal and the inverted input signal are inputted to the level shifter, and the equalization unit is turned on; wherein after the reset phase, the equalization unit is turned off and the level shifter starts to shift a level of the input signal.
