摘要： The present invention discloses a voltage level shifter capable of interfacing between two circuit systems having different operating voltage swings. The voltage level shifter comprises an input buffer having a low supply voltage for inverting an external input signal to an internal input signal, and an output buffer having a high supply voltage for inverting the internal input signal to an external output signal. The high level of the external input signal is lower than the high level of the external output signal. The voltage level shifter is designed such that the input buffer is operating to achieve a low-leakage and high-speed performance.
