ABSTRACT:
A digital system includes apparatus for propagating falling and rising edges of a digital signal through two separate data paths each optimized to maximize propagation of one edge of the signal. The first data path is structured to propagate the first transition (e.g., falling edge) of the digital signal with a delay less than that experienced by the second transition (rising edge); and the second data path is structured to propagate the second transition with much less delay than that experienced by the first data transitions. The outputs of the two data paths are applied to a combining circuit, and put together to form a final representation of the digital signal to use the first and second state transitions as propagated by the apparatus.
