Abstract
An integrated semiconductor VLSI chip design that increases the number of driver circuits, or groups of driver circuits, that can be simultaneously switched. Timed driver gating signals, or driver enable signals, are used, in conjunction with physical grouping of driver circuits on the chip, to isolate switching drivers from quiet drivers. This construction and arrangement minimizes detrimental effects usually caused by noise that is generated when driver circuits switch.
