Josephson voltage standard
![](https://en.wikipedia.org/wiki/Special:FilePath/JJ_Steps_low_and_high_capacitance.jpg?width=300)
A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement, is the basis for voltage standards around the World.
