Is there some formula or scientific basis to estimate noise levels as a
function of pixel size? At the moment I'm assuming that noise levels
decrease with the square root of the size increase, i.e. doubling the
pixel area should lower noise levels by the square root of 2. Is this
correct? I'm only referring to "pixel" noise, i.e. not read noise, A/D
conversion noise and other external noise sources.
