Abstract
An evaluation phase expansion system for increasing the operating frequency of a dynamic logic circuit which includes a plurality of logic stages. The plurality of logic stages are partitioned into a first set of logic stages which are responsive to an early clock signal and which evaluate in an early evaluate phase and a second set of logic stages which are responsive to a late clock signal and which evaluate in a late evaluate phase. The late evaluate phase of the late clock signal commences during the early evaluate phase of the early clock signal and terminates during an early pre-charge phase of the early clock signal in order to artificially induce clock asymmetry to compensate for logic asymmetry in alternating pipeline phases of the dynamic logic circuit.
