Abstract
A level shifting circuit for a voltage level translator includes first and second cross-coupled level shifters, each coupled between an output supply voltage and a lower rail and further coupled to receive first and second input control signals and to provide an output control signal. The second cross-coupled level shifter includes a first PMOS transistor coupled in series with a first NMOS transistor and a second PMOS transistor coupled in series with a second NMOS transistor. When an input supply voltage is less than a VCCI trigger associated with the output supply voltage, only the first and second NMOS transistors are coupled to contribute to the output control signal and when the input supply voltage is equal to or greater than the VCCI trigger, only the first and second PMOS transistors are coupled to contribute to the output control signal.
