Abstract
A level shift includes a bias voltage providing circuit, a level shifting circuit and an output switching circuit. The level shifting circuit includes a high level shifting unit and a low level shifting unit. When the high level shifting unit is in a cut-off state, the high level shifting unit further receives a first bias voltage such that the high level shifting unit is in a partially cut-off state, accordingly increasing a response speed of the high level shifting unit. When the low level shifting unit is in a cut-off state, the low level shifting unit further receives a second bias voltage such that the low level shifting unit is in a partially cut-off state, accordingly increasing a response speed of the low level shifting unit. The level shifter of the present application provides a higher response speed.
