Solid-State Electronics
Noise which can produce erroneous transitions in Josephson logic devices can be treated in terms of the familiar model for thermal activation of a particle over a potential barrier. Noise curves are calculated which represent the effective threshold curves for a given transition rate; this approach can be applied to the mode-to-mode (superconducting) transitions as well as to the mode-to-voltage state switching. The analysis will be illustrated with the example of a three-junction current injection device. The practical consequences for design of Josephson, logic circuits will be indicated. © 1983 IEEE
