Level shifter and driver circuit including the level shifter
A level shifter includes a current mirror configured to receive an input signal in response to a first power voltage and generate an output signal by mirroring a current corresponding to a second power voltage based on a level of the input signal, a first adjusting circuit coupled to an output terminal of the current mirror and configured to adjust a voltage level of the output terminal of the current mirror in response to a bias voltage, and a second adjusting circuit coupled to a power voltage terminal which receives the second power voltage in parallel to the current mirror and configured to adjust the voltage level of the output terminal of the current mirror.
