在分析现有静态结构双边沿触发器和动态结构双边沿触发器优缺点的基础上,该文提出了半静态结构双边沿触发器设计。PSPICE模拟表明,新设计功能正确。与以往一些设计柏比,新设计在功耗、速度、功耗延迟秘以及减少MOS晶体管使用数目等方面都具有明显的优势,从而使新设计具有良好的综合性能。该文的另一个贡献是对双边沿触发器性能的测试方法进行了探讨,提出了测试双边沿触发器最高频率的新方法。
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.
