Deadtime

I have been looking for schematic of deadtime circuits, but with no result..

i'm using a single LM833N opamp for carrier and for comparing, i have MIC4420 that i use for mosfet driving, and a couple of different fets i would like to try..

so is it possible that you can find or make me a deadtime circuit? ..
- perhaps a short explanation on what to change to change deadtime..

well you have driver for only one fet, you can't have deadtime with only one...but still you can use same circuit, just 1/2 of it

I made a test, but i'm not sure that it is correct.
If take my pwm from my opamp and comperate it in two parts an look at in my scope, i can variate the gab between them, is this my deadtime (the blue area).. when no there is no gab there is no DC between the points, if a bigger gab, bigger DC voltage..

Hi Bender !

I'am very interested about this http://www.diyaudio.com/forums/showthread.php?postid=1346365#post1346365

Can you post scematic and PCB layout??

Nice job!!

its another way

Next carrier based damp version. 80-90V per rail max, short circuit protection, nothing special 🙂.

I like that

Hi all. Here is my light version of Fredos Damp.

Hello Bender.ru
can you send your pcb and shematic to my email PLZ?
i really want to have one class D amp like that.
thanks
