  • Patent number: 6448829
    Abstract: A low hold time flip-flop that has a dynamic input stage and a static output stage is provided. The flip-flop uses a feedback stage to maintain a value on a dynamic node during an evaluation phase of the flip-flop so that an input to the flip-flop only has to be held for a relatively short period of time after the start of the evaluation phase.
