ABSTRACT:
Briefly, in accordance with one embodiment of the invention, a slew rate control circuit for a processor includes: a circuit configuration to produce a signal representing the speed of fabricated transistors; and a circuit configuration to adjust, based at least in part on the signal representing the speed of fabricated transistors, the amount of current produced by a pre-driver stage for an output buffer of the processor. Briefly, in accordance with another embodiment of the invention, an integrated circuit includes: a slew rate control circuit for a buffer including: a register capable of storing at least one binary digital signal, a pre-driver, and at least one pre-driver cell coupled to the pre-driver. The at least one pre-driver cell is coupled to the pre-driver and register so as to modify the amount of current produced by the pre-driver based, at least in part, on the at least one binary digital signal.
