In this paper, a novel low-power dual edge-triggered (DET) D-type flip-flop is proposed. This design achieves dual edge-triggered with two parallel data paths work in opposite phases of the clock single. Among them, a latch circuit structure employs differential input data signals which deposits very little capacitance on the clock line is accomplished. For fair comparison, four previously reported DET flipflops along with the proposed DETFF (DET flip-flop) are compared in terms of power consumption and power-delay product (PDP), under different data activities and different data rates. Several HSPICE simulation results show that the proposed DETFF is superior in power reduction at different parameters as compared to the existing DETFFs. Hence, the proposed DETFF is well suited for low power applications.
