Re: Commentable Thoughts
Im trying this myself, but how does one adjust dead time in this manner?

Do you want to make deadime adjustment by the use of two comoparator, right ?
You can only do this properly with carrier-based amps. You simply use different reference levels for both comparators.
You can see this on a very old schematic of minr that I have posted on this forum somewhere.
I'll have to find it agin first.

Yes, deadtime adjustment by two comparators. It is carrier based.
By differnt reference levels, do you mean the carrier (triangle wave) is shifted higher up ( a DC offset) before it enters the other comparator?
Would this be done by decoupling the triangle wave before entering one comparator and then add a DC voltage on to it?

Australian ISPs blow hard in an unconventional way, don't they.
I feel your pain, and so does my other friend down there.
