DOUBLE EDGE TRIGGERED MODIFIED HYBRID LATCH FLIPFLOP (DMHLFF)

In this paper a new low power flip-flop called Double-edge triggered Modified Hybrid Latch Flip-Flop (DMHLFF) has been proposed and compared to previous flip-flops. DMHLFF is a low power, low area, and fast flip-flop. Power consumption is reduced by avoiding unnecessary internal node transition. Power consumption in clock tree is also reduced by decreasing the frequency of clock to half f the cock frequency in single edge triggered flipflop for the same throughput. These capabilities are obtained by modifying the structure of conventional Hybrid Latch Flip-Flop without any penalty in area. Reducing the number of transistor in stack leads to having less delay and thus higher operational speed compared to others flip-flops
