Abstract
A high speed output buffer including an input circuit providing first and second signals within a first voltage range having a first common mode voltage, an AC interface receiving the first and second signals and providing first and second preliminary drive signals, a detection and correction circuit that corrects a state of the first preliminary drive signal AC coupled to the first signal, first and second drive circuits receiving the preliminary drive signals and providing first and second drive signals, where the first drive circuit operates within a second voltage range having a greater common mode voltage and where the second drive circuit operates within a third voltage range, and an output that switches an output node within a voltage range that is greater than a maximum voltage range. The first, second and third voltage ranges are each within the maximum voltage range suitable for thin-gate devices.
