摘要:
A low power level shifter circuit for high performance integrated circuits includes an input inverter operating in a domain of a first voltage supply and receiving an input signal and a design structure on which the subject circuit resides is provided. An output stage operating in a domain of a higher second voltage supply includes a first output inverter connected to the input inverter and a second output inverter connected in series with the first output inverter. The second output inverter provides a level shifted output signal having a voltage level corresponding to the second voltage supply. A series connected finisher transistor and finisher control transistor are connected between the second voltage supply and an input to the first output inverter. The finisher control transistor is activated responsive to the input signal. A path control transistor controls a path between the first voltage supply and the input inverter. The path control transistor being activated responsive to the level shifted output signal.
