Hey,
just came across a link on DIYaudio forums about the sudbury neutrino detector preamplifiers... Apparently, they are super-low noise (<<0.3nV/sqrt(Hz) and <<1fA/sqrt(Hz)) but the funny thing is the report was open access 5 years ago; not so anymore! Cant even find any literature describing it in much detail! Any pointers?? Or is it super-classified, for-your-eyes-only now? The idea is I want to know if anyone has heard of a 100mW (total DC power, that is!) amplifier that has sub-nanoVolt and sub-femtoAmp input noise specs... or anything in the vicinity...
