I want to design edge triggered flip flops, such as a D flip flop. I found that there are two main topologies about edge triggered flip flop designs. One is master-slave flip flop. The other is to use a clock pulse train to clock the level triggered flip flops. Obviously, the second choice is much simple and easy to design. However, I found most of text books normally discuss the master-slave flip flops. This makes feel that the clock pulse train topology is not recommended, easy to fail. So what are the advantages and drawbacks of each topology? which one is more safe, i mean it is difficult to fail? which topology is widely used? Thanks a lot!!!!!
