Patent ID: 7994819

Claim:
A level-shifter circuit comprising: 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, wherein the control stage comprises a first transistor that interconnects the first control node and a resistor and is driven by the input signal; and a second transistor that interconnects the second control node and the resistor and is driven by a complement of the input signal, wherein the current flows through one of the first and second transistors based on a logic state of the input signal; a logic driver that is coupled to the second control node and is referenced in a high voltage domain, the logic driver being 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; and further comprising a first resistor that interconnects a high voltage domain logic-high rail and the first control node and a second resistor that interconnects the high voltage domain logic-high rail and the second control node, the first and second resistors having approximately equal resistance magnitudes.
