Traceable precision pA direct current measurements with the ULCA
Hansjörg Scherer, Gerd-Dietmar Willenberg, Dietmar Drung +2
A standard method for picoammeter calibrations is the capacitor charging technique, which allows generating traceable currents in the sub-nA range. However, its accuracy is limited…
