Abstract

Nonlinear current-injection switching of Josephson interferometer devices is achieved by current injection into an asymmetric feedpoint. This method of switching interferometers has two important features: higher gain than in previous approaches and a novel nonlinear threshold curve which is of practical interest. A new family of high-performance logic gates based on nonlinear current injection is described. Logic circuits have been experimentally tested and preliminary results are presented.

Current Injection Logic Gate with Four Josephson Junctions

S. Takada, S. Kosaka, Hisao Hayakawa

A novel current switching Josephson logic gate in which four junctions are connected in a loop is described. This four-junction logic gate can reduce an inductance included in the loop as small as possible, so that the higher switching speed and the smaller device size is expected. The switching threshold and the switching characteristics of the gate are investigated both theoretically and experimentally. Logic circuits based on the gates are also experimentally demonstrated.

High-tolerance three-Josephson-junction curent-injection logic devices (HTCID)

H. Beha, Heinz Jäckel

A new 3-Josephson-junction interferometer is presented as a high-tolerance nonlinear current-injection 2-input AND gate. In Josephson LSI circuits, the tolerances are an important issue. Thus, in our new logic device emphasis has been placed on its static and dynamic tolerance properties. The new HTCID offers considerably better input-signal tolerances than known 2-junction current-injection devices (CID) for identical fabrication tolerance assumptions. The HTCID in this example has a Josephson current ratio of 1:3:1 and a characteristic phase λ = 0.72π. Including circuit parameter variations, this new 3-junction CID allows attractive, high input-signal tolerances of ± 33.3%. Therefore, an almost threefold tolerance improvement over the published 2-junction CID (λ = 0.66π) could be achieved. Trade-off between signal tolerances and device speed is discussed. Computer simulation indicates a worst-case delay of less than 47 ps.

Variable threshold logic with superconducting quantum interferometers

Norio Fujimaki, Hiromasa Hoko, H. Shibayama +2 more

This paper proposes a two-junction interferometer called Variable Threshold Logic. It has both magnetically-coupled control-lines and current-injection terminals. The threshold curve of this gate can be shifted by the applied currents. This property enables its use for both OR and AND function with the same structure by only changing the wiring. Operating margins of ±12 % for OR and ± 29 % for AND are obtained with the optimized device parameters. Any logic circuit can be obtained by Josephson master-slice LSI of this gate with a dual-rail logic system.

A novel current injection Josephson logic gate with high gain

K. Hohkawa, Masaru Okada, Akira Ishida

A novel Josephson logic gate achieving high gain, employing current injection, and having a noninterferometer configuration has been proposed and studied. The gate includes three small junctions for input sensing, output driving, and I-O isolation. The junctions are appropriately biased by source resistors to obtain high current gain. Computer simulation and preliminary experiment have demonstrated that a current gain higher than 2 can easily be obtained through the proposed configuration.

Josephson compensating junction logic

C.J. Anderson

A Josephson superconducting quantum interference device (SQUID) digital logic family was developed that uses the R/sub nn/ region of a Josephson junction (JJ) to compensate for variations in where R/sub nn/ is the effective resistance of a JJ in the linear I-V region beyond the gap. The basic compensating junction logic (CJL) circuit is two 2-input-OR 1-2-1 interferometer isolators that, when switched, inject current into a 2-input-AND 1-2-1 interferometer. The R/sub nn/ region of several JJs is used in series with a resistor to set the current from the power supply to the 2-input-OR interferometers. The 2-input-AND interferometer is implemented with both current injection and magnetic coupling. The latch circuit uses both current injection and magnetic coupling design techniques to increase the range of I/sub O/, inductance, and resistance variation over which the latch will function correctly. Experimental measurements of CJL circuits are described.>

Josephson dual rail two-bit adder circuit utilizing magnetically coupled OR-AND gates

Hirotaka Yamada, Yoshichika Ichimiya, Akira Ishida

A novel Josephson logic gate called the asymmetrical interferometer device (AID) is presented. It is composed of a pair of asymmetrical interferometers whose outputs are injected into a single junction. The interferometers are individually operated as two input OR and the single junction is worked as AND.(A + B) (C + D)operation is accomplished by only one AID gate. They have a serial fan-in capability due to their magnetic coupling scheme. The gate size is reduced by half, compared with the previous current injection logic (CIL) gate. With these AID gates, a high-speed two-bit dual rail adder circuit is configured, which provides the logic circuits performing with both true and complement inputs and without any timing circuits. The AID gate fabricated by standard 5-µm Pb-alloy technology showed a wide margin over ±20 percent that was in good agreement with statically designed characteristics. Experimental adder operation was also successfully performed.
