ABSTRACT:
A level shift circuit includes a level shifter, the level shifter configured to receive input signals and generate level-shifted signals by level-shifting the input signals, an output buffer that includes a first sourcing circuit and a first sinking circuit, the first sourcing circuit and the first sinking circuit being connected in series between a first power and a second power, a first buffer coupled between the level shifter and the output buffer, the first buffer configured to buffer the level-shifted signals and provide a first driving signal to the first sourcing circuit, and a second buffer coupled between the level shifter and the output buffer, the second buffer configured to buffer the level-shifted signals and provide a second driving signal to the first sinking circuit.
