ABSTRACT:
A pulse generator utilizes a Josephson junction gate circuit having first and second control current paths for conducting control currents in opposite directions. An input signal applied to one of the control current paths will transform the Josephson junction device to the voltage state resulting in the leading edge of a pulse output from a branch circuit connected in parallel with the gate current path of the Josephson junction device, and the same input pulse passed through a delay circuit will be applied in the opposite direction to the other control current path to thereby switch the Josephson junction device back to the zero voltage state and cause the trailing edge of the pulse output. The delay device can be a .pi. circuit, a single additional Josephson junction device having its control current path connected either in series or in parallel with the one control current path of the first Josephson junction device, or a plurality of cascaded Josephson junction devices.
