Abstract
A current-switched gate is described which comprises two Josephson tunnel junctions and a small resistor in a triangular loop. Directly combined bias and control currents flow through one junction in the zero-voltage state, causing the switching. The second junction and the resistor provide isolation between input and output after switching. Switching speeds of a few tens of picoseconds and the microwatt power dissipation are attained. Latching as well as nonlatching schemes and memory circuits are described.
