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