Abstract :
This paper describes no-race charge-recycling differential logic (NCDL) which realizes low power computation with less sensitivity to input signal skews. Performance comparison with previous charge recycling logics is shown for a 2-input NAND logic. NCDL operates in push-pull mode and achieves about 35% improvement in power-delay product over full swing differential logic without the pre-evaluation problems. Thus, it shows increased effectiveness for the implementation of random logic with input signals arriving in an arbitrary sequence
