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.
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 flipflop that consists of two ECL memory-gates. On the basis of the above theory,a five-carry shifting counter ~s designed using such D master-slave flip-flops. The above theory and circuits are verified through computer simulation.
