And do you think that the professor publishes papers without doing that? As an academic, he would be more inclined than ever to do so. He gave me a quick off the cuff opinion about a question I asked, but I can't imagine him being surprised by that question. It would not be a stretch to assume that he has long ago thought long and hard about it. As I said before, his knowledge and experience has to be respected.In engineering, expert "opinion" without proof doesn’t mean much. We settle things with physics, math and rigorous proof.
You mean the forward current gain β? That is not what we were discussing. We are talking about the causal relationship of the voltage and current. If I come across that book, I will certainly look at it to see if it applies to what we are talking about.In their book, Analog Integrated Circuits, Paul Grey and Robert Mayer develop an expression for forward current gain that does not include any terminal voltages, only device and physical parameters. It does not matter that the input has a voltage/current relationship; every device does.
I think I stated before that design and calculation work well with the concept of current control. The causal relationship does not.I trust the experts here, like Mr. Eric Gibbs, who has spent a half-century designing electronic products, over any arbitrary achedemic "expert".
I said in my previous post that I once believe as you do. So of course the opinion he gave me was counter to my own. I don't own or operate a semiconductor laboratory, so my "research" is reading and evaluating what other "experts" publish. The professor was an expert source of knowledge, so I was not wrong is asking his opinion.It actually sounds like he gave you an opinion that was counter to how you believed. You should have just done your own research.
