Hello all,

I'am trying to design a circuit that convert from analoge to PWM with a fixed 10 MHZ frequency!!

can anyone help what will be the component of this circuit and how it looks like ?

Thanks;

Did you struggle to come up with this title?

What are you going to PWM at 10MHz?

Ha ha ha, true that, this topic is better.

I like duty cycles, and I want to make analog to PWM convertor with a fixed 10 MHZ frequency, I have an idea but I dont know if it's correct or not by using a comparator with an input with triangular wave with f=10 MHZ, and that voltage analog on the other side will be the output of PMW with f=10MHZ ... is that correct? I have tried but seems dont work.

Show us your circuit inlcluding IC specifications.

Can you run 100m in 8 seconds?

You realize that the comparator must swtich in about 1 ns to make this work. I.e. 1% of the PWM frequency. And I repeat CDRIVE's question, whiy 10MHz? That is a bit high.

Well, I like hot blonds but what does this mean?

It means you have something in common with Newt Gingrich.

I'm getting slower by the day and I confess that I didn't get this initially. Yes she is!
