Abstract

A Josephson voltage standard based on a series array of 2076 junctions is described. When irradiated with a 15-mW signal at a frequency of 96 GHz, the array produces 15 000 quantized levels between −1.5 and 1.5 V. Initial results on high-precision comparisons with a Zener reference standard are given.
