反馈式ECL记忆门的记忆性能和移位计数器
Memory Property of a Feedback ECL Memory-Gate and ECL Shifting Counter
【摘要】 经过数学论证表明,改进反馈式ECL(MFECL)门可在二个状态中任一态保持稳定,所以认为MFECL门就是一种ECL记忆门或D锁存器.提出了一种由两个ECL记忆门组成的ECL主从D触发器.在上述理论基础上,利用此主从D触发器设计出5进制移位型计数器.经过计算机模拟上述电路,验证了理论和电路的正确性.
【Abstract】 By mathematical proof,we identify a modified feedback emitter-coupled logic (MFECL) gate with an ECL memory-gate or D latch,because the MFECL gate is able to keep steady either of two states.Then we present a D master-slave flip-flop that consists of two ECL memory-gates.On the basis of the above theory,a five-carry shifting counter is designed using such D master-slave flip-flops.The above theory and circuits are verified through computer simulation.
