In this paper, we describe Parallel Dynamic Logic (PDL) which exhibits high speed, no charge sharing problem. PDL uses only parallel-connected transistors for logic evaluation and is a good candidate for high-speed low-voltage operation. It has less back-bias effect compared to other logic styles which use stacked transistors. Furthermore, PDL needs no signal ordering nor tapering. PDL with speed-enhanced skewed static logic renders straightforward logic synthesis without area penalty due to logic duplication. Our experimental results on two 32-bit carry look ahead adders using 0.25 μm CMOS technology showed that PDL with speed-enhanced skewed static (SSS) logic improves performance over clock-delayed (CD)-domino by 15-27% and power×delay by 20-37%.
