ABSTRACT:
A dual stage voltage level predrive circuit for an integrated circuit chip including two level shifter stages in series. The voltage level shifting circuit uses single dielectric layer devices and three bias supply circuits each providing a different DC bias voltage for distributing bias voltages among the devices such that dielectric voltage stress across single dielectric layers is reduced. The first stage of the level shifting circuit receives a first input signal having a first voltage swing, converts the first voltage swing to a second voltage swing and provides a first output signal corresponding to the first input signal and having the second voltage swing. The second stage of the level shifting circuit receives the first output signal from the first stage, converts the second voltage swing to a third voltage swing and provides a final output signal having the third voltage swing.
