I don't think so. What makes you think that read-noise std.dev. scales quadratic with pixel pitch. Please, provide some rational for this behavior.

This is based on explanations by bobn, you'll have to ask him for details. But I have seen anybody showing that this premise as first order assumption was incorrect. And it does not sound unreasonable to me that read noise could be partly based on a phenomena that is proportional to the size of the pixel.

It seems that I could not find Bob's explanation anywhere. Could someone point me to it. Or better if bobn2 could weight in himself.
