ABSTRACT:
A chopper/stretcher circuit provides on-chip clock distribution with minimum insertion delay. The on-chip clock chopper/stretcher circuit triggers only on the transition of an off-chip generated clock input and determines the generated pulse width of the clock by means of an on-chip delay line. The circuit introduces only one stage of delay in the clock path.
