Hi Jim, all you want can be made discrete or with opamps.
If you know transistors, some parts can be designed much easyer.
This is why my analogue converter uses much of them.
There was one stage I was thinking of an opamp use. But it gave
no advantage.

Kat, please beleve me, a 2K2 is not a save pull down for TTL inputs!

Kind regards
Darius
