Low Noise Voltage Source
Could someone elaborate on "bridge configuration"? Links? Thanks everyone, Paul- paulpoosk

Low Noise Voltage Source
IRstuff, thanks a lot for your suggestions. However, my goal is to perform this experiment without a lock-in amplifier. jtdsamuels, do you have any links to these sites that you mention? How about any circuit schematics of an instrumentation amplifier? Thanks.- paulpoosk

Low Noise Voltage Source
It does not need to go all the way up to 2V.- paulpoosk

Low Noise Voltage Source
I was incorrect at first...the noise is 10-15mV. I am applying 0-2V to 50 ohm load, with a need to detect changes in resistance of less than 1 ohm. The idea is to retrieve an M-R transfer curve by monitoring the load.- paulpoosk

No, I don't think a low ripple power supply is an option.- paulpoosk

Low Noise Voltage Source
Hi, All: I am monitoring the change in resistance of a load (~50 Ohms) with respect to a varying applied magnetic field (changes R_load by fractions of an Ohm). I would like to bias a constant voltage across this load to monitor these changes. I am having difficulty maintaining a low-noise...- paulpoosk
