I have been thinking of try to cool down some op-amps and see how
much this helps noise. Some of the lowered noise amps
tend also to get hotter. Anybody try this?
l also work with some Hamamatsu photodiode cameras. These things
have bias circuits which also tend to have more noise with biasing,
however the newer cameras have a new bias circuit suppy thats putting
a 440 hz noise spike. I wanted to try cooling this camera, maybe
also get rid of the bias circuit. A little scary working wwith $15K stuff.
