ABSTRACT:
A programmable delay generator produces a composite delayed pulse from an input pulse, and the leading edge of the composite delayed pulse is controlled by a voltage comparator with a variable reference voltage level supplied from a digital-to-analog converter; however, an OR gate determines the trailing edge of the composite delayed pulse with a delayed input pulse supplied from a delay circuit so that the trailing edge is independently controllable regardless of the time delay introduced by the voltage comparator.
