Hi all. I want to make a positive and negative edge trigger circuit. May you guys help me...
First of all the goal is to trigger clock pin of a d flip flop (cd4013). The project is just about to learn something interesting.
Incıming signal is variable square wave %50 duty cycled. I want to generate a clock signal from that square wave. Every changing edges (rising & falling) the circuit will generate a pulse for clock pin of the flip flop. It will not change by input frequency. By the way bedore i wrote here , i also tried to do some but it wasnt desired one. The scheme is here ;
This circuit is working on high freq about 200hz-25 khz. But on less is not working well. I have also changed caps and resistor different type of values but the result didnt changed. In theory it was working. And also tried with ltspice. All things working as i desired. But in pratic ...
Some of the websites also mentioned sometihng like that;
But this time in simulation softwares the time width is too small then i wanted to generate.
So i thought you guys may help me about that. If you have any spesific diagram for that , i can take it gladly
Edit: The reason why im not using D Latch is all i want to do generate edge trigger.
