Abstract :
Digital to analog converters based on the Josephson effect are promising for voltage standards, because they produce voltage steps with ultimate precision and stability. We are currently developing an SFQ-Based D/A converter (RSFQ-DA), designed for synthesizing a sinusoidal waveform for metrological applications. In this report, we examine a feasibility of an ac-dc transfer difference measurement for a thermal converter using the RSFQ-DA.
