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.
