Abstract

A ramp generator includes a master counter repeatedly ramping through for ramp-intersect operation of a digital pulse generator, while firing at the intersection, or when above the reference will cause a complementary digital change to define with the master counter count a ramp count on a subsequent ramp and adjacent zone below, thereby to adjust rapidly to a fast change of reference.
