Review of Dual-Edge Triggered Low-Power D Flip-Flops

The most recent dual-edge triggered flip-flops forlow-power applications are reviewed in this paper. The Dual Edge triggered flip-flops(DETFFs) can sample the data at twice the rate compared to Single-Edge triggered flip-flops, which can sample at both positive and negative edges of the clock. The parameters such as power, power delay product, Clock to Q delay, and minimum voltage of operation are calculated in this work for various DETFFs at standard conditions. This will help the reader to understand different types of DETFFs and what to use depending upon the application of interest. This work also focuses on calculating power by adding an extra test driver circuit to the main design for accurate values.
