Abstract
Process voltage temperature compensation are used for a bus driver; specifically, a PCI-X 2.0 DDR Standard bus driver. Performance is improved by enhancing the speed of the PCI-X buffer by removing the statically controlled gate stages and providing for output signal slew control by dual use of on-resistance of signal pass transistors. Although directed to PCI-X technology, this circuitry may also be used in SCCI, controlled impedance drivers, and other buffers, where short propagation delay and signal integrity are of concern.
