Thanks much! Very interesting study!

Although it does not affect the results within their assumptions, I'd point out that the authors in most cases analyzed circuits using negative current feedback instead of the negative voltage feedback concept they started with. This makes the load (and feedback) resistors' frequency dependences influence on their results harder to visualize; and the feedback circuits have higher, instead of lower, output impedance compared with the non-feedback versions.
