ABSTRACT
A conventional positive-edge-triggered flip-flop (FF) senses and responds to the control input or inputs at the time the clock input is changing from 0 to 1. It does not respond at all to changes in the opposite direction. Negative-edge-triggered FF's behave in a complementary manner. Thus, these FF's can respond at most once per clock pulse cycle. It is proposed that double-edge-triggered (DET) FF's, responding to both edges of the clock pulse would have advantages with respect to speed and energy dissipation.
