本文通过对常用的电菏控制主从触发型J-K触发器和时钟脉冲下降沿触发J-K触发器的波形分析,从脉冲的时序关系出发,论述时钟脉冲的最高工作频率与触发器平均传输延迟的对应关系,以及触发器输出端Q、(?)波形对延迟的影响,此外,还对输出波形上产生的“缺角”、“双峰”等畸变现象作了说明,并提出了提高J-K触发器工作频率的一些设想. In this paper, we analyze the waveform analysis of the JK flip-flop triggered by the master-slave triggering JK flip-flop and the falling edge of the clock pulse, and discuss the relationship between the maximum operating frequency of the clock pulse and the average transfer delay of the flip-flop , And the influence of the waveform of the output Q, (?) Of the flip-flop on the delay. In addition, the phenomena of distortion such as “missing corner” and “bimodal” produced on the output waveform are described, and the improvement of the JK flip-flop Some ideas for working frequency.
