The design and testing of a very low noise, high accuracy, programmable voltage reference is presented in this paper. This piece of instrumentation, which can be controlled by a personal computer via the built-in RS232 interface, is intended as an alternative to batteries in the realization of automated low frequency noise measurement systems. The supply voltage ranges from 0 to 5 V with a resolution and long-term stability better than ±250 μV. The power spectral density of the output voltage fluctuations is less than 10-16 V2/Hz at 100 mHz and remains below 10-17 V2/Hz above 1 Hz.

Abstract
The design and testing of a very low noise, high accuracy, programmable voltage reference is presented in this paper. This piece of instrumentation, which can be controlled by a personal computer via the built-in RS232 interface, is intended as an alternative to batteries in the realization of automated low frequency noise measurement systems. The supply voltage ranges from 0 to 5 V with a resolution and long-term stability better than ±250 μV. The power spectral density of the output voltage fluctuations is less than 10-16 V2/Hz at 100 mHz and remains below 10-17 V2/Hz above 1 Hz.File in questo prodotto:
