Nonhysteretic josephson junction circuits with feedback
Patent
·
OSTI ID:6535820
The transfer characteristic of nonhysteretic josephson junction gates is sharpened and desired switching behavior free from resetting requirements is achieved by a positive feedback scheme in which the gate is made to be responsive to current flow in the output line. Specific applications to three-junction interferometers are described as are various means for rendering the gate, responsive to the output, I.E., magnetically coupling the output line to the gate, adding a portion of the output current to the control lin, and injecting a portion of the output current directly into the gate.
