Domino logic (original) (raw)

Domino logic is a CMOS-based evolution of the dynamic logic techniques based on either PMOS or NMOS transistors. It allows a rail-to-rail logic swing. It was developed to speed up circuits, solving the premature cascade problem, typically by inserting small and fast pFETs between domino stages to constrain the interstage cascade velocity to a curtailed maximum—a curtailed deterministic maximum—without requiring other circuit design interlocks.
