  • Abstract
    At SCL, an automated system is developed to calibrate DC current sources and meters, including electrometers and femto-ammeters, from 100 pico-amperes (pA) down to 100 femto-amperes (fA). The system comprises an in-house developed control software, a ramping voltage generation circuitry and a precision air capacitor.
