Talk:Return ratio

Observations
Some comments to improve the article:

1. Return Ratio (T) = - Loop Gain (L), they are equal in magnitude, but different sign in the case you mentioned.

2. I think the example is good; considering ro as well as RS, since both resistors (although in this case in parallel with others) are important when dealing with input/output impedances.

3. I also agree in that RD should be called RC, to follow the traditional nomenclature for the BJT (just as VCC).

Simplifying example
I think it would be clearer if the example could be simplified. -Roger (talk) 20:21, 28 January 2008 (UTC)
 * A simpler transistor model neglecting ro would make the figures and equations more compact and at no real loss of generality since ro is just in parallel with RD (why's it called "RD"?)
 * RS could also be neglected

Improved simulation methods
Two recent and improved simulation methods for the return ratio (or loop gain as I prefer to call it), Tian's method and Middlebrook's General Feedback Theorem (GFT), are described on my webpage http://www.geocities.com/frank_wiedmann/loopgain.html.

Undone recent edit
I undid a recent edit, as it fouled up the page pretty bad, formatting wise. Please read Referencing for beginners for more info on how to do it right, or ask here or the Help desk for more specific help. -- Jayron  32  06:07, 6 February 2012 (UTC)
