Differential, mixed swing, tristate driver circuit for high performance and low power on-chip interconnects

摘要

A driver to provide low voltage swings on a bus with fast switching times, the driver comprising two pairs of pullup and pulldown nMOSFETs, each pair operated in complementary fashion to each other, each pair with a high voltage rail at a smaller voltage than the data input logic HIGH voltage, and where each substrate of the nMOSFETs are biased so as to reduce their threshold voltages.
