ABSTRACT:
A voltage level shifter circuit, comprising diodes to provide a voltage buffer to reduce output voltage swings, and edge detection circuits to momentarily turn on pull-up pMOSFETs so as to speed up the voltage level shifting at input signal transitions and to mitigate static power dissipation. Other embodiments are described and claimed.
