F8 has no phase splitter. (JLH Q2)
That is a very significant difference

if we go step further, we can compare it with Loftin-White



and just a little toe more, with anything having 3 resistors and 1,5 actives in it

nature of things when you are in stripping business

Just got finished reading the latest article.
Only dumb people are able to find it.

The phase splitter is not necessary a disadvantage.
Can even be an advantage.

Not saying which is better just that it's a significant difference
JLH has something like 2.5 or 3 gain stages depending on your definition.
F8 has 2 gain stages.

It's Different not really similar.

Phase splitter has no gain.
But whatever pleases you.




Cheers,

That would be like saying there is no voltage gain out of the input transistor of a folded cascode front end.

Pretty sure you have voltage gain out of the collector of Q2 which then goes to the base of the upper transistor Q4 which provides some current gain.
Out of the emiiter of Q2 you have current gain and then voltage gain on the lower output device Q3.
Pretty sure that's what you have.

If you consider a gain of -1 is gain, then yes.
Phase Splitter - Electronics-Lab.

I shall also stop.

My point was it's bloody different.

I'm not wrong.


You chose to argue over something totally unrelated.
