Just do it

You obviously have no idea what control theory is or designing audio.
user 37518 said:What I usually use (and believe most of us do) is the Gain/Phase margin analysis of the loop gain, which seems to me to be much more intuitive than a root locus, Routh-Hurwitz stability criterion or Nyquist plot
Its an inverting integrator
I might if I knew what that is. :-(sahib said:A better example is our JR. I did not hear him saying how he used control theory to design the amplifiers he designed.
sahib said:It does not teach you how to design an amplifier. As long as you know how to design the building blocks of an amplifier and put them together, and know Ohm's and Kirchhoff's laws, you are set for life. Your design and simulation package will take care of the rest. You do not need to know anything about control theory. If you do (which I know a bit) yes it helps you understand the theory better.
user 37518 said:Also, one of the greatest books on OPAMPs is the one by Roberge, and it is extremely heavy on Control Theory. I think of it like this, you can be an extremely good car mechanic without knowing physics, but if you want to be a great car designer, you will probably have to know the laws and use them..
sahib said:I have got it in my library. It is a very heavy book. But I have heavier books than that in terms of circuit analysis.
I do not wish this to drag on too long as people are probably getting bored. But you are still making analogies to car design etc and I do not think this will get us anywhere. So, I will agree to disagree and bow out.

I have nothing against drifting, on the contrary. Sometimes it is advisable to start a new topic, so the OP doesn't get entangled in sectarian squabbles that make them going to GS for comfort.sahib said:As it often happens here in this forum, the discussion drifted away from the main issue.
Indeed, I will just apologize for mentioning it in the first place and leave it at that.sahib said:I do not mean to blame but I was merely trying to say that asking somebody, who could not even understand what a capacitor does in a circuit, to start with control theory was surely not needed.

Who would have thought the OP's innocent question would result in such controversy, as I'm sure both of you are well-meaning.

That's right, but I know too well, having been guilty of it, and not sure I'm vaccinated against it that sometimes a single post is enough to inflame a debate.user 37518 said:I only made 3 posts in this thread,

I deleted my first post, and hopefully there are enough other links / suggestions to get the OP started.
