Hi Vatche, I looked through your derivations and it's a bit awkward but the final result kind of contradicts my intuition. Referring to my schematic if C1 is...
Hi Svilen, Yes, when I factored 1+C2/C1 in the numerator, I made a mistake in the coefficient of 1/s - apparently I factored it as 1+C1/C2. Hence, w_z should...
No, I didn't mean it that way. I meant that it left an awkward feeling because it didn't match what I expected to be the frequency behavior of the impedance....
Hi All, Awkward or not, it triggered me to get into the discussion! One of my colleagues once said that the difficulty with Middlebrook´s algebra is to keep...
Hi Nils, Your thoughts on this subject are quite similar to mine. I have the feeling that for the 3EET, 4EET and so on, one will again get the high-entropy...
Hi, Actually this was also my initial intention for asking about the way to go if I wanted to add a third capacitor to the circuit. I feel comfortable in...
To all, The NEET is more indispensible than the 1EET or 2EET. Whereas you may still have a prayer to work out a cricuit with two reactances using the old...
Hi, For the benefit of all, here are some links relative to Vatche's message: The book he mentions is of course <http://www.amazon.com/dp/0521624428>....
From: David Middlebrook. Hi Svilen: In a recent Message, which I can't find, you asked about what makes an EET reference TF viable. For some unknown ...
Hello, Dr. Middlebrook reported to me that many members of the D-OA group are not receiving emails from the group. I have sent email to those probably not...
Hello, I think it's time to release a new DVD with live presentation of: "Middlebrook's New Structured Analog Design Course" Any time shedule for this? Thanks,...
From: David Middlebrook. Yes, I do intend to add audio narration to the New Structured Analog Design Course. It's a lot of work, and I have several projects to...
Hi Frank, I am Carlos and am new here in the group. It might be strange that I am getting into a very old discussion but I found it very interesting, first to...
Hi Carlos, I completely agree with you. T and Tn are of course very useful for designing feedback circuits. One should only be aware that if one sees a...
From: David Middlebrook. Hi Frank: About the Gray et al book [1] and the Wikipedia article [2]: Yes, they show the formula and block diagram for a single...
A while ago I had read the message #116 I vaguely recall and I forget what exactly it had but there was some good idea. Is there a way to find that message or...

Sir, I am novice engineer working in DC-DC switching power supplies.For that please send me the Files accessible to Group Members that are the Final reports...
Hello; I'm new to the group, but I'm hoping to jump into this discussion. I'm trying to understand how to apply the GFT for hand analysis of feedback...
From: David Middlebrook Hi Rob: The purpose of the GFT is to dissect the gain H of a feedback system into three transfer functions (TFs), the ideal closed-loop...
From David Middlebrook. Hi Rob: My Message #161 was a brief reply to your #159. I've made a followup, which I've uploaded as a File under Middlebrook Articles ...
hope u r well I searched on internet(google ) for the middlebrooks closed transfer function and for open loop but didn't find any thing to fulfill my needs...
 Hi,  I have a question about bode plot measurement setup of a switching converter.  In measuring the close frequency response of a dc/dc converter, it...
