In short, how do we implement the GFT methodology within spice engine? Is there an obsolute necessity of post-processing? Which document is the nearest of an...
From: David Middlebrook Here's a brief history of the GFT (General Feedback Theorem). A hardware implementation of loop gain measurement by test voltage...
... Thank you for your fast reply. During last week-end, I deeply get in chap 8-11. I figure most of the underlying of the analysis approach and better ...
From: David Middlebrook. There is no restriction on the use of the GFT. Anyone can implement it in any circuit simulator. Intusoft was the first to do it, and ...

Hi Dr. Middlebrook, Thank you very much for posting this file. I have gone through the example on page 3 of your handout by hand to convince myself about the...
From: David Middlebrook. Mark, I'm out of town until July 15 so you've forced me to rederive the inequalities for Case 2! You're right: (4) is not needed. This...

Hi Dr. Middlebrook, I appreciate you going through the exercise while you were traveling. I agree that the new inequality condition you have come with below...
Hello, Some time ago, there was a request for GFT simulations in a simple SPICE simulator. I have developed a method for this and have implemented it in the...
From: David Middlebrook. Hi Frank: I was very interested to see your Message #37 on the Yahoo Group D-OA. I hope this will spur some further discussion of the...
Hi David, I got interested in the subject of feedback when I discovered the new stability (stb) analysis in Spectre. Soon afterwards, I found Tian's article...
From: David Middlebrook. Hi Frank: I agree with almost all your interpretations, in both of your Messages #37 and #41. I also am left with many of the same ...
Hi David, Thanks for your detailed response. I agree with you that the question about the true loop gain has little meaning. All loop gain definitions that...
From: David Middlebrook. Hi Frank: You say "Not all loop gains satisfy Tian (3). For example Tfwd and Trev do not…" I agree, but when they are combined as T...
Hi David, I completely agree with everything you wrote. What I would like to point out, however, is that there might be people who are using a specification...
