Notes:
We have constructed an extremely low noise constant current power supply. The design was optimized for low noise at 0.5 Hz. For a 134 mA supply, noise at this frequency is 2.5 nA rms/ (square root of)Hz. At 1 Hz, it is 1.0 nA rms/(square root of)Hz. The supply is roughly an order of magnitude quieter than the quietest commercial unit we know of.
