Abstract
An edge triggered latch has an improved transparency window, which is essentially the delay of the N-stack pull-down tree. This minimizes the delay yet guarantees that the circuit will have enough time to evaluate the input data, since the evaluation is limited by the pulse width. This circuit eliminates early mode failure for latches placed in series, without the requirement of delay padding.
