Comparative delay, noise and energy of high-performance domino adders with stack node preconditioning (SNP)

Stack node preconditioning (SNP) and "mutex" techniques for charge-sharing noise reduction are incorporated into the critical path gates containing transistor stacks in 32-bit domino adders to simultaneously improve best achievable performance by 10% and reduce charge-sharing noise by 2/spl times/ in circuits containing transistor stacks.
