Abstract
The present invention discloses a level shift circuit which comprises: level shift means for receiving an input of a first operational voltage and generating an output of a second operational voltage; and a current path connecting with a source of the second operational voltage and providing current to the output of the level shift means to speed up output level switching. The circuit preferably further comprises a power consumption control circuit for stopping excess power consumption when the output of the level shift means has substantially accomplished level switching.
