Patent ID: 7002392

Claim:
A method for converting a signal from a low voltage domain to a high voltage domain, comprising: receiving an input signal in a low voltage domain; using the input signal, controlling a first transistor having a first carrier type, a second transistor having a second carrier type different from the first carrier type, and a third transistor having the second carrier type to produce an output voltage at an output terminal, wherein controlling comprises applying the input signal to at least one control transistor operable to control at least one of the second and third transistors; dividing the input signal into two portions, wherein the first portion of the input signal is applied to the control transistor; inverting the second portion of the input signal; and applying the second portion of the input signal to a gate terminal of the first transistor, wherein: the first transistor is coupled to the output terminal and further coupled to a first voltage corresponding to a first value in a high voltage domain; the second and third transistors are coupled in series between the output terminal and a second voltage corresponding to a second value in the high voltage domain; and the output voltage is selected to correspond to either the first voltage or the second voltage based upon the input signal.
