Hello everyone! Please help me to understand a thing: if I want to use my op amp to generate a triangle wave with max 20kHz (classical design, op amp + schmitt trigger comparator) what is the right op amp bandwidth?
I would say 1MHz is enough (this is what I want to use), but my friend says you need two other decades so at least 2 decades (therefore 2Mhz).
What would you chose and why?
