Abstract :
A 4-bit superconducting shift register based on edge triggered gates has been tested up to 11 GHz with two-phase offset sinewave clocks. The edge triggered gates are made by serial connection of a Josephson junction (JJ) and a modified variable threshold gate, fabricated by a Nb/AlO/sub x//Nb process.<>
