EUP7903 数据手册DataSheet 下载
... The EUP7903 is designed specifically to work with very small ceramic output capacitors. A 1uF to 10uF capacitor with 5mΩ to 500mΩ ESR range is suitable for the most EUP7903 applications. The ESR of a typical 1uF ceramic capacitor is around 20mΩ, which easily meets the ESR requirement for stability. ...

Electric Circuits: Potential difference (Grade 10
... Lets look at two resistors in parallel more closely. When you construct a circuit you use wires and you might think that measuring the voltage in dierent places on the wires will make a dierence. This is not true. The potential dierence or voltage measurement will only be dierent if you measure ...

Josephson voltage standard
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.
