Skew-Tolerant Circuit Design

Domino Circuits

Static circuits built from transparent latches remove the hard edges of flip-flops, allowing the designer to hide clock skew from the critical path and use time borrowing to balance logic across pipeline stages. Traditional domino circuits are penalized by clock skew even more than are flip-flops, but by using overlapping clock phases it is possible to remove latches and thus build domino pipelines with zero sequencing overhead. This chapter describes the timing of such skew-tolerant domino pipelines and the design of individual domino gates.
