I made the first revision of this article, but I'm not very satisfied with it. The model was found in course material from Holland; firstly a cource given by Catena Microelectronics, then a "book" by Verhoeven and others. Both these originated fact-wise from a PhD thesis by Ernst Nordholt, who later wrote the Catena course material. I wrote the article to aid my own understanding of the subject, hoping that others would later fill in.
Things that need to be checked or clarified: Is the term asymptotic gain model used elsewhere, or was it invented by Nordholt? How does the terminology and model relate to the works of Black? How is the model useful for design?
The "book" by Verhoeven and others was later made into a real book ( ISBN 1-40-207590-1), which is now for sale. I don't have it. Hopefully the dimension problems have been solved. -- HelgeStenstrom 13:31, 24 Sep 2004 (UTC)
Sorry but I couldn't really salvage the previous article so I rewrote it. The equations and symbols are all different, but I'm sure they refer to the same thing. I based my article on "Feedback Amplifier Principles" by Rosenstark and various other IEEE papers, especially those by Middlebrook. There's still alot content that needs to be added (e.g. an article on return ratio and an example would be nice), so help would be appreciated. Roger 20:07, 14 May 2007 (UTC)
Good advice, but equally applicable to any circuit theorem. -Roger ( talk) 19:40, 25 January 2008 (UTC)

I think my perspective was not understood. Finding the current gain first is the simple way to go, and then make connection with the transR gain later. There is no reason to make transR gain the primary choice. The short-circuit current gain allows determination of gain for any output variable choice. Brews ohare ( talk) 23:31, 25 January 2008 (UTC)

The Asymptotic Gain Model is very closely related to the General Feedback Theorem (GFT) developed by R. David Middlebrook. A short introduction and a number of relevant links are available in the corresponding section of my webpage http://www.geocities.com/frank_wiedmann/loopgain.html.
