Abstract :
A circuit has been designed to determine if on-chip path delays are equal to a pre-specified target. The circuit uses a delay-locked loop to generate the target delay, combined with a phase detector to determine the delay of a path in comparison with this target delay. The circuit was implemented with 0.18 um CMOS and has been analyzed over process, supply, and temperature variations. Accuracies in delay detection are within 200 ps.
