The charge might be multiplied before the readout amplifier, which would
mean that the readout noise wouldn't change with ISO setting. There are
some so-called zero readout noise sensors that use a similar technique
(but the devices are currently exotic and mostly experimental; I doubt
anything like this is done in any consumer cameras).

I have seen some stuff in a Marconi presentation, but I was under the
impression that it introduced its own "multiplier" noise and that it was
quite complex. Agree that it sounds way beyond the current technology
deployed in digital cameras.
