A Sawtooth waveform generator controlling a nMOS acting as a LED dimmer.

Shake your mobile phone to run the circuit!

Unfortunately it seems the EC app is having trouble on finding the convergence point. (Also happens sometimes on softwares like multisim) making the simulation """broken""".

If you want a sawtooth waveform, you and you this simple circuit: http://everycircuit.com/circuit/6406913804992512

But don't use a sawtooth waveform to turn on and off a MOSFET. That makes no sense whatsoever. And why are you using an NMOS for high side switching!?

I think I misunderstood the high-side config. purpose. But could you please explain to me why it is nonsense to use a waveform to switch a MOS? I believe I failed to learn something.
