Dynamic transistor gate overdrive for input/output (I/O) drivers and level shifters
Abstract:
An apparatus for generating an output voltage signal based on an input voltage signal. The apparatus includes a first field effect transistor (FET) including a first gate configured to receive a first gate voltage based on the input voltage signal; a second (FET) including a second gate configured to receive a second gate voltage based on the input voltage signal, wherein the first and second FETs are coupled in series between a first voltage rail and a second voltage rail, and wherein the output voltage signal is produced at an output node between the first and second FETs; and a gate overdrive circuit configured to temporarily reduce the first gate voltage during a portion of a transition of the output voltage signal from a logic low level to a logic high level.
