Josephson arbitrary waveform synthesizer : realisation of a quantum standard for ac voltage (JAWS)

Objective

The problem addressed in this project is the lack of instrumentation and knowledge for accurate and traceable measurement and generation of alternating (AC) voltage with arbitrary waveforms. The objective is to develop a standard that is based on a Josephson Arbitrary Waveform Synthesiser (JAWS), a high-precision instrument that directly links the generated voltage to the Josephson effect. Technological developments in telecommunication and sensor industry and the manifest trend towards miniaturization of electronic circuits induce an increasing demand for traceability of small voltage signals. In contrast to the existing-DC and AC standards the intended JAWS will operate precisely in this range (up to 10 mV). A European approach is needed and will lead to cohesion on the quality of electrical measurements since all countries will in the longer term use the same coherent instrumentation.
