my take on the szekeres - Page 9

Here is the missing schematic from the thread:

That looks just like an example of Jung's composite opamps type amplifier.
A voltage gain opamp driving a current gain opamp (here a FET source follower).
Is that a correct interpretation?

That's pretty much correct.
Any op amp followed by a buffer could be traced back to Jung.

Interesting. I know what I'm working on is nothing novel; after browsing the forum and several others, it looks like a buffer wrapped inside the NFB loop of an opamp accounts for two out of every three designs.

Figured I'd do my part and make my own version.

There are plenty of options for new versions.
If you include discreet op amps followed by a buffer you
could probably push the number up to 80% or more...
