Error estimation in recording I–V characteristics of Josephson junctions
Abstract
A method for characterizing a current total step in the I-V characteristic of a Josephson junction array is considered. In this method, an appropriately selected approximating curve is statistically fitted to the experimentally found curve. A self-calibration algorithm for an array of junctions incorporated into programmable voltage standards is suggested.
