测量系统和其他应用中通常需要超低噪声电压源。普通电压调节器在某些应用中表现不佳。作为替代方案，已经使用电池单元。在各种类型的电池中，汞电池被认为性能最好。然而，据我们所知，电池中电压噪声的实际值尚未报道。本文讨论了一种能够测量低于-200 dBV/Hz的电压噪声的测量系统，并探讨了它在实验上表征高性能基准电压源的能力。这种测量的结果对常见的电池，并考虑潜在的应用。
Ultra low noise voltage sources are often required in measurement systems and other applications. Common voltage regulators have performed inadequately in some applications. As an alternative, battery cells have been used. Of the various types, Hg cells have been credited with the best performance. However, actual values for the voltage noise in batteries have not, to our knowledge, been reported. In this paper a measurement system capable of measuring voltage noise below -200 dBV/Hz is discussed and its ability to characterize experimentally high performance voltage references is explored. The results of such measurements on common batteries are presented, and potential applications are considered.
