Sub-10 ps high-gain direct coupled Josephson logic gate
Abstract
A cascade chain of high-gain direct coupled logic gates with a 25 x 20 sq micron gate size was designed and fabricated using Pb-alloy Josephson technology with Josephson junctions of 3 micron diameter and 2 micron line-width resistors. Logic delays as low as 9 ps and power-delay products as small as 30 aJ were experimentally obtained.
