Abstract
A level shifter is provided. The level shifter includes a first input transistor, a second input transistor, a first bias transistor, a second bias transistor, a first switch transistor and a second switch transistor. At the time of change of the signal status, by raising the potential of the body terminal of the first input transistor, the threshold voltage is reduced so that the current flowing through the second input transistor is increased to shorten the time of the change of the signal status.
