Abstract
A level shifter circuit included in a computer system may include bootstrap and feedback nodes. The level shifter circuit may discharge the feedback node in response to high-going transition on a received input signal generated using a first power supply signal. The level shifter circuit may also increase a voltage level of the bootstrap node in response to the high-going transition and charge the bootstrap node, in response to the discharge of the feedback node, to a voltage level of a second power supply signal that is different than a voltage level of the first power supply signal. The level shifter circuit may generate an output signal using the voltage levels of the feedback node and the second power supply signal.
