ABSTRACT:
A variable keeper strength based process-compensated dynamic circuit and method provides a robust digital way to overcome the intrinsic parameter variation present in manufactured die. Using a process-compensated dynamic circuit, the wide robustness and delay distribution becomes narrower which improves performance without sacrificing worst-case robustness. The strength of the keeper is programmed depending on the amount of die leakage. The keeper will have an optimal strength for the best and worst case leakage, allowing better performance with improved worst-case robustness.
