One day I penned a piece about that. It is here:

Funny, the article says Simon Joinson.

Anyway, it has some issues. The biggest one is that the logic used to say that since a tiny 10MP sensor is much smaller than a large 10MP sensor, that this necessitates smaller pixels for the smaller sensor, and therefore that is the reason for more noise. That is not true at all. A tiny 0.4MP P&S sensor with 10 micron pixels would have far more image noise than a FF sensor with 8 or even 1 micron pixels.
