ABSTRACT:
An Asymmetric Sense-Amp Flip-Flop (ASAFF) is disclosed that may achieve zero setup time and short clock-to-Q delays. The ASAFF captures input data at a clock transition by setting values of a first node and a second node in a manner that is input data value dependent. If the input data is at the first input data value, the first node is set and held at a first storage value after a first delay, and the second node is set and held at a second storage value after a second delay, and if the input data is at a second input data value, the first node is set and held at a third storage value after a third delay, and the second node is set and held at a fourth storage value, after a fourth delay. This internal-path dependent difference in delay enables ASAFF to achieve zero setup time.
