Oh, just go ahead and say what you always say. I know you're thinking
it.

Since he requested this, I would expect him to say "thanks."

Sure. Now I remember what response you're trying to elicit from me,
See...

"TwistOnCockcroftWaltonPump.pdf" on the S.E.D/Schematic Page of my
website... been there more than 5 years.

And "CMOS-Osc-NoClip.pdf"... from 13 years ago.

That's what you were expecting? Right ?>:-}

Not trying to elicit it, but fully expecting you to say it anyway.

I don't know if it's better but I can't compare directly because it has
a different multiplier, so more components.

What are those D2A buffers?

Considering that it's a negative multiplier, if you used TTL to get more
drive would the source current be the limiting factor, so the extra sink
current wouldn't help?

The cap value is dictated by the output current and droop, but if one at
an early stage was smaller that would have the same effect as making
them all smaller, right?

Why this? He already has a clock that doesn't clip.

No. "Where are the values?" It doesn't matter because it has to be
recalculated anyway for different applications, but that's what I
expected.

Thanks John, I wasn't sure about the C's and D's.
I scribbled something that looked like a cockroft-walton.

There are a few different looking topologies.

An old patch I devised to get from PSpice's logic 0->1 outputs to
0->5V, no longer needed

Considering that it's a negative multiplier, if you used TTL to get more
drive would the source current be the limiting factor, so the extra sink
current wouldn't help?

I'll have to come up with a 555 version.
