Abstract :
In this paper, we propose two novel dual edge-triggered flip-flops. One design eliminates redundant transitions of internal nodes when current data is the same as the previous one. This has the least power delay product compared to other dual edge-triggered flip-flops in all range of possible data switching activity and its delay is also the smallest. The other proposed flip-flop disables internal clocked transistors. When data switching activity is within 20%, it has the least power consumption
