Towards quantum AC voltage standard

Jari S Penttilä, P. Helistö, Heikki Seppä

We have studied the possibility of realizing AC voltages with metrological accuracy. In this paper we propose two experimental setups for generating accurate sinusoidal voltage waveforms from square-wave biased nonhysteretic programmable Josephson array voltage standards.

Series arrays of NbSi barrier Josephson junctions for AC voltage standards

J. Kohlmann, Oliver Kieler, Thomas Scheller +3 more

AC Josephson voltage standards are typically based on series arrays of overdamped Josephson junctions, which are presently realized using an NbxSi1-xbarrier at PTB. The characteristic parameters of these SNS-like junctions can be tuned by the Nb content and the thickness of the barrier over a wide range for operation from 10 GHz to 70 GHz. Based on these junctions, we developed binary-divided 10 V arrays as well as pulse-driven arrays for 1 V output voltages.

4-bit Bipolar Triangle Voltage Waveform Generator Using Single-Flux-Quantum Circuit

Tomoki Watanabe, Yoshitaka Takahashi, Hiroshi Shimada +2 more

SFQ digital-to-analog converters (DACs) are one of the candidates for AC voltage standards. We have proposed SFQ-DACs based on frequency modulation (FM). Bipolar output is required for applications of AC voltage standards, while our previous SFQ-DACs generated only positive voltages. In this paper, we present our design of a 4-bit bipolar triangle voltage waveform generator comprising an SFQ-DAC. The waveform generator has two output ports. Synthesized half-period waveforms are alternately generated in one of the output ports. The bipolar output is realized by observing the differential voltage between the ports. We confirmed a 72-μVPP bipolar triangle voltage waveform at the frequency of 35.7 Hz.
