Design of D flip-flops based on multi-threshold neuron

By analyzing the principle of muti-threshold neurons（MTNs） with hard limiter,a method was developed for designing D flip-flop in MTNs.First,a latch was designed by using single MTN.Second,two MTNs were employed to design the master-slave D flip-flop,whose output data could be transferred just one time in one clock cycle.Compared with universal ways of implementing D flip-flop in single-threshold neurons,the proposed design based on MTNs could reduce the number of neurons and connecting lines,and decrease complexity and improve stability.With this D flip-flop,arbitrary functions of sequential circuits in neuron network can be achieved.
