To erase redundancy of the clock, improve clock utilization rate and reduce power dissipation, this paper proposes the logic design of low power flip-flop based on double edge trigger.
从消除时钟冗余，提高时钟利用率以达到降低功耗的思想出发，提出基于双边沿触发的触发器的逻辑设计。
The parallel loading of the flip-flop can be synchronous (i. e., occurs with the clock pulse) or asynchronous (independent of the clock pulse) depending on the design of the shift register.
触发器的并行加载可以是同步的(即在时钟脉冲到达时发生)或异步的(不依赖于时钟)，这取决于移位寄存器的设计。
Especially, the clock-racing multi-threshold flip-flop can decreases the leakage power and the power dissipation of clock network.
特别是多阈值时钟竞争型触发器，不仅可以降低电路的漏电流功耗，还能降低电路的时钟网络的功耗。
