Abstract:
One embodiment of the invention includes a level-shifter circuit. The circuit comprises a control stage that steers a current from one of a first control node and a second control node to the other of the first control node and the second control node based on an input signal to set a first initial voltage at the first control node and a second initial voltage at the second control node, the input signal having logic-high and logic-low voltage magnitudes that occupy a low voltage domain. The circuit also includes a logic driver that is coupled to the second control node and is referenced in a high voltage domain. The logic driver can be configured to provide an output signal having logic-high and logic-low voltage magnitudes that occupy the high voltage domain based on the second initial voltage.
