Abstract
A level shifter includes an input end being capable of receiving an input voltage signal. The input voltage signal includes a first state transition from a first voltage state to a second voltage state. An output end can output an output voltage signal having a second state transition from a third voltage state to the second voltage state corresponding to the first state transition of the input voltage signal. A driver stage is coupled between the input end and the output end. The driver stage includes a first transistor and a second transistor. Substantially immediately from a time corresponding to about a mean of voltage levels of the first voltage state and the second voltage state, the second voltage state is substantially free from being applied to a gate of the first transistor so as to substantially turn off the first transistor.
