You seem to be making the assumption that equivalent ISO settings on small sensors can be made available by increasing their full well capacity.
Class A, sorry, I missed your question.
I think we agree and you misread something in the paper. I actually state that equivalent ISO settings will be unavailable in small systems in general, showing the case of the FourThirds system.
As long as a given sensor is made with the same tech, its total full well capacity (sensel FWC times #pixels) scales with d^2. I don't say otherwise.
I only mention that theoretically, a smaller sensor
could be made thicker (in an attempt to make it the same cost) to compensate and provide similiar DR. I say too that market forces don't allow this to happen.
So I think, we agree on everything here
P.S.
I applaud Sony to make the 36MP FF sensor ISO 100 (even ISO 50 in extended mode). There have been too many ISO 200 FF sensors to shave off a bit off the cost. I assume the D800 will be a DR monster exceeding 15EV DxO DR and beating any other camera including MF and D4.
