You design the electronics to make the read noise as low as practical, but there are always tradeoffs.

One of the biggest tradeoffs is readout time: for larger sensors if you want lower read noise you need slower readout or more expensive ADCs. That is one reason why the more expensive Atik cameras have higher read noise -- they tend to have larger sensors.
