Hi everybody,

I got this group project in college that we should find a high level design of a pulse width modulator for a certain application and then design a low level design. But it is very important that it should be an analog PWM not a digital one.
I have been searching in the internet for days, and could hardly find anything.

Does anybody know any special site which has got something like a database of
schematics??? Or could somebody please refer me to a good website?

Thank you

Our Ebook has an experimenter analog PWM circuit - http://www.allaboutcircuits.com/vol_6/chpt_6/9.html.

 

In the Projects Collection forum, I added a very simple analog PWM driver circuit a couple of weeks ago. It's somewhat unusual in that it uses a digital gate in an analog mode.
