Validation of the ultrastable low-noise current amplifier as travelling standard for small direct currents
Dietmar Drung, Christian Krause, Stephen P. Giblin +7
An interlaboratory comparison of small-current generation and measurement capability is presented with the ultrastable low-noise current amplifier (ULCA) acting as travelling stand…

Validation of a quantized-current source with 0.2 ppm uncertainty
Friederike Stein, Dietmar Drung, Lukas Fricke +11
We report on high-accuracy measurements of quantized current, sourced by a tunable-barrier single-electron pump at frequencies up to GHz. The measurements were performed wi…
