I want to build a simple PWM Circuit using Op-Amp which takes +15 -15V input and gives a square wave output 0 to +15V whose frequency should be variable and may range from few Hz to KHz/MHz and the duty cycle should also be variable.
If any one can provide any help or any schematic diagram then I would be quite thankful..
