ABSTRACT:
A variable width pulse generator includes a plurality of logic stages which are coupled in cascade. Each stage is arranged to select one of a plurality of clock signals of differing phase applied thereto responsive to particular bits of a data word defining the pulse width. All of the stages are initially disabled by a precharge pulse occurring at the beginning of each variable pulse interval. The successive stages are enabled by the occurrence of a clock pulse of a clock signal selected by the previous stage. The lastmost stage provides an output corresponding to the variable width pulse.
