Timing constraints for domino logic gates with timing-dependent keepers.

Timing constraints for domino logic gates with timing-dependent keepers.

Low threshold voltage (Vt) can be applied to domino logic to improve the performance in dual threshold voltage technology. Then, the keeper transistor should be up-sized to compensate for reduced noise margin due to the significant subthreshold current of low Vt transistor. However, a large keeper t...
