Input buffer/level shifter

摘要

A circuit is presented comprising a first device and a second device. The first device may be configured to operate at a first supply voltage and may be configured to generate a pull-up signal in response to an input signal. The second device may be configured to operate at a second supply voltage. The second supply voltage may be lower than the first supply voltage. The second device may be configured to generate an output in response to (i) the input signal and (ii) the pull-up signal.
