T. Umezawa et Y. Higashino, DESIGN AND TESTING OF HIGH-TC JOSEPHSON PULSE DRIVER USING SELECTIVE SEJS, IEEE transactions on applied superconductivity, 5(2), 1995, pp. 2809-2812
We have designed a novel Josephson pulse driver based on SFQ circuits
using high-Tc junction parameters, and fabricated it using selective S
EJs. Simulation showed that the output pulse can be stepped up to 2.5
mV, which is 13 times larger amplitude than the input pulse. In the fa
bricated driver using microstrip line, two dozen SEJs were integrated
with Au resistors and inductor, then it operated at 77 K with a conver
sion factor of (1-1.5) at best.
