| Zusammenfassung | This article presents experimental evidence for a very low bias current dependence on the fundamental component for a sum of square wave signals synthesized by a Programmable Josephson Voltage Standard (PJVS). The typical bias current dependence due to the transients can be suppressed, as has been theoretically predicted [1]. Measurements show that the sum of square wave signals has a slope of less than 20 nV/mA (relative voltage change of 2 × 10-8 for a bias current trim of 1 mA) within the quantum voltage step at 1 kHz and 1-V level.
