Abstract
Level-shifter circuits and methods of using the same are provided. A level-shifter circuit includes a latch unit and a level-shifting unit. The latch unit is configured to generate a latch signal for storing a logic state of a first digital signal in a first power supply domain. The level-shifting unit is configured to shift a voltage of the latch signal to output a second digital signal in a second power supply domain. The latch unit and the level-shifting unit are powered by a power supply voltage in the second power supply domain.
