关于做为电压基准(尝试室尺度电池)的电池,见Weston电池和Clark电池.
克拉克尺度电池是由约西亚·拉蒂默·克拉克在1873年创造的一种湿式化学电池,能产生高度不变的电压。1893年,克拉克电池在15摄氏度时的输出被国际电气大会定义为1.434伏,那必然义在1894年成为美国的法令。那个定义后来被基于威斯顿电池的定义所代替。
Weston 惠斯顿尺度电池是一种湿式化学电池,产生高度不变的电压,合适做为校准电压表的尝试室尺度。它由爱德华·惠斯顿(Edward Weston)在1893年创造,从1911年起头被接纳为国际尺度,曲到1990年被约瑟夫森电压尺度所代替。
在电压基准芯片之前,高精度的电压基准是如何产生的?若是您不给一个时间限造的话, 最起头电子管也是有电压基准的。
半导体的高精度的电压基准是用的齐纳二极管,
例如 LTZ1000 (贵)或者 LM399 (廉价)。
国内的细密稳压二极管有 2DW234 稳压管及 2DW7稳压管(用两个温度系数相反的管子串联停止抵偿)。
