Abstract
A semiconductor integrated circuit device includes a level-shifting circuit, a current mirror circuit and a switch circuit. The level-shifting circuit level-shifts an input signal having a first amplitude to an output signal having a second amplitude. The current mirror circuit charges or discharges an output node of the level-shifting circuit. The switch circuit operates the current mirror circuit during a period from the inversion of the input signal to the inversion of the output signal.
