摘要
提出了两种新型脉冲触发器结构——EXPAND触发器和EXPAND-TG触发器.同传统结构相比,新结构一方面通过减小中间节点电容提高电路充放电速度,另一方面通过消除信号竞争避免直流短路电流对电路速度和功耗的影响.同其他文献报道的结构相比,新结构在功耗和速度上均有明显的改进.
The speed and delay of flip-flops are critical to the performance of digital circuit systems. Two novel structures for dualedge triggered explicit-pulsed flip-flops are proposed in this paper. The charging and discharging times are greatly reduced due to the lower capacitance of the interval nodes in the new structures, and the short circuit power consumption is diminished by overcoming the race problem as well. The flip-flops are also superior to the structures reported in the literature in terms of both power dissipation and working speed.
