thank you.
i need ultra fast pwm pulse for drive ultra_fast gate driver ic.for ultra fast power mosfet drive.
Actually i need a pwm with 100khz _ 1Mhz squre pulse with 5_20 ns rise & fall time.
What circuit may be such a thing?
Thank you for help me.
1 MHz square wave with fast rise time is no problem as rise time is mainly achieved by the driver. 30 ns pulse width would require additional logic or a faster processor.

It's a simple issue on timming analysis; If you have to update the PWM duty-cycle at each cycle, you have to ensure that the maximum loop of instructions of the AVR core will not exceed the period of the PWM.
