Abstract Based on analysis of traditional static and dynamic Double Edge-Triggered Flip-Flops (DETFFs), a new semi-static DETFF is proposed in this paper. PSPICE simulation shows that the proposed DETFF has correct operation. Compared with traditional static DETFFs, the proposed DETFF has significant improvement in terms of power, speed, Power-Delay-Product (PDP) and area. In addition, the performance measurement of the DETFFs is also discussed in this paper, and a new approach is proposed for testing the maximum working frequency of the DETFFs.
