Abstract
A voltage-level shift apparatus includes a first level shift unit, a second level shift unit, a charging unit, and a discharging unit. The first level shift unit receives a reference voltage and a power voltage to output a level-shifting voltage. The second level shift unit is connected to the first level shift unit and receives the level-shifting voltage. The charging unit receives a control voltage to provide an output voltage. The discharging unit is connected to the charging unit and receives the control voltage and the reference voltage. When the control voltage turns on the charging unit and turns off the discharging unit, the charging unit is charged by the level-shifting voltage. When the control voltage turns off the charging unit and turns on the discharging unit, the discharging unit is discharged from the output voltage.
