Abstract

This paper summarized recent results of our work towards developing a voltage standard based on high-temperature (HTS) Josephson junctions array. The concept of a programmable HTS voltage standard and technological aspects of fabrication are discussed. New circuits providing uniform microwave current distribution along the HTS array are suggested.
