Abstract:
This invention operates to select a drive code for an adjustable drive strength transistor in a drive buffer. The drive code is determined employing a scaled-down drive transistor employing varying drive codes compared with a standard. The thus determined drive code is combined with an offset to generate the drive code for the adjustable strength transistor.
