| Zusammenfassung | The noise and stability of a commercial current source is limited by the quality of components used for construction, such as the voltage reference chips, resistors, and power supplies. A state-of-art commercial current source typically exhibits a stability no better than parts in 107. In this paper, we present a way to implement a current source with external (with respect to the power supply) electrical references. This approach allows the current source stability to be decoupled from the noise characteristics of the main power supply circuit. A few parts in 1E8 stability is demonstrated here. |
