  • Abstract
    We have designed and tested a very low-noise, high-accuracy programmable voltage reference that is intended as an alternative to batteries for the realization of automated low-frequency noise measurement systems. The output voltage, which can be set via a built-in RS232 interface, ranges from 0 to 5 V with a resolution and long-term stability of ±250 μV. The power spectral density of the output voltage fluctuations is less than 2·10-16 V2/Hz at 100 mHz and remains below 10-17 V2/Hz above 1 Hz.
