Hello dear friends
It might be something odd, but I am looking for a low price design that can have a 30khz PWM output with a variable duty cycle.
What I have simulated so far is this method, but the simulation in Proteus doesn't work in 30khz output. Is it the problem with Proteus or something else is it? As for the opamp, I chose lm833. Omitting the third opamp will show the triangular output.
Your help is really appreciated.
