Cryogenic small-signal conversion with relaxation oscillations in Josephson junctions
Cryogenic small-signal conversion with relaxation oscillations in Josephson junctions
Broadband detection of small electronic signals from cryogenic devices, with the option of simple implementation for multiplexing, is often a highly desired, although nontrivial task. We investigate and demonstrate a small-signal analog-to-frequency conversion system based on relaxation oscillations in a single Josephson junction. Operation and stability conditions are derived, with …
