ABSTRACT:
The speed of a level shifter, which translates a first voltage in a first power domain to a second voltage in a second power domain, is increased by utilizing a first bipolar transistor to assist a first MOS transistor in pulling down the voltage on a first output node, and a second bipolar transistor to assist a second MOS transistor in pulling down the voltage on a second output node.
