That one is even better, a standard out of thin air.. but that guy knows, what he is doing..

For all non-German members:
The guy is describing the process of building his voltage reference using a pretty sophisticated German writing style combined with some nice pictures. The author uses his language abilities to justify his freestyle 3D layout which ressembles some electronic device that has accidentally suffered from a waste press treatment.
http://www.amplifier.cd/Technische_Berichte/Spannungsnormal/images/Leiterplatte.jpgWhat really strikes you is the lack of parts and source information.
The author deliberately leaves out any hint on that kind of information although it's obvious by looking at the pictures which parts he is using.
His built description qualifies as entertainment only - you won't find any usable information you could learn from when building your own reference. The degree of show off becomes obvious once you read the translation below:
[...
die Spannungsrefenzen sind ein bekannter Typ, der den fachkundigen Lesern bekannt ist - die Nennung spart man sich. Das
The voltage references are of a known type which is known to knowledgable readers - I save my breath to quote them.schöne an diesen Exemplaren ist, sie hat einen Date Code aus dem Jahr 1991, unbenutzt und richtig alt (so alt kaum erhältlich) - ein
The good thing with these parts is, it has a date code form 1991, unused and really old (hardly obtainable that old)schönes Gefühl, so lange natürlich vorgealterte Exemplare zu bekommen. Die Kunst mit diesem Referenztyp ist nicht das "Kaufen",
a good feeling to get naturally preaged parts. The art with this type of reference is not the act of buying sondern danach das "richtig machen", hierüber finden sich im Internet viele, teils sehr gute Diskussionen.
"but the right doing afterwards", about this matter there can be found lots of discussions on the internet, partly very good ones.Eine weitere IC-Referenz, die beim Distributor derzeit schon für ca. 90 Euro verkauft wird
Another reference IC, being sold at distributor level already for approx. 90 Euros now...]
If you like the entertainment aspect of pseudo-science promoted by the awesome soldering expert with his proprietary soldering spraying techniques (improves EMP transient handling O0) or the German voltage reference developer with the nice pictures you could as well read across the now disfunctional page of self-proclaimed krypto expert Detlef Granzow:

Have fun reading!
