Hi EDA members,
I want to design a 8 phases non-overlapping circuit from johnson divider by 4 circuit. I already referred to this post for a hint:
But the thing is my clock input has constraints that I cannot make it as large as i want:
For example I have a source of fi=4 GHz and want 8 phases output signals with DCD = 12.5 % non-overlapping, f0=1GHz. The simple solution is just to use a divider by 8 circuit with fi=8GHz, then i have f0 = 1GHz with 8 phases as desired. However i don't have such big clock source of 8GHz. How can I solve this problem with this condition?
Very much appreciated your help!
Tommy
