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.

Claim (Index 6):
The level-shifter circuit according to  claim 2 , wherein the level-shifting unit comprises:\n a third inverter, having an input terminal configured to receive the latch signal; a first switch, having a control terminal and configured to turn on in response to a logic high at the control terminal and to turn off in response to a logic low at the control terminal, wherein the control terminal is coupled to an output terminal of the third inverter and a first terminal of the first switch is grounded; a second switch, having a control terminal and configured to turn on in response to a logic high at the control terminal and turn off in response to a logic low at the control terminal, wherein the control terminal receives the latch signal and a first terminal of the second switch is grounded; a third switch, having a control terminal and configured to turn on in response to a logic low at the control terminal and turn off in response to a logic high at the control terminal, wherein the control terminal is coupled to a second terminal of the second switch, a first terminal of the third switch is coupled to the first terminal of the first switch, and a second terminal of the third switch is coupled to the power supply voltage in the second power supply domain; and a fourth switch, having a control terminal and configured to turn on in response to a logic low at the control terminal and turn off in response to a logic high at the control terminal, wherein the control terminal is coupled to a second terminal of the first switch, a first terminal of the fourth switch is coupled to the first terminal of the second switch, and a second terminal of the fourth switch is coupled to the power supply voltage in the second power supply domain.
