Circuit Description and Design Flow of Superconducting SFQ Logic Circuits
Superconducting Single-Flux-Quantum (SFQ) devices have been paid much attention as alternative devices for digital circuits, because of their high switching speed and low power consumption. For large-scale circuit design, the role of computer-aided design environment is significant. As the characteristics of the SFQ devices are different from conventional devices, a new design environment is re...
متن کاملDemonstration of an optical interface for SFQ logic circuits
Single-flux-quantum (SFQ) logic circuits are expected to be operative at a clock rate above 100GHz with very low power consumption. A considerable amount of research has been performed on this topic, and noteworthy achievements, e. g. 120 GHz shift register [1] and microprocessor consists of over 10,000 junctions [2], have been reported recently. With the progress of the performance of SFQ circ...
متن کاملComparisons of Synchronous-Clocking SFQ Adders
Recent advances of superconducting single-flux-quantum (SFQ) circuit technology make it attractive to investigate computing systems using SFQ circuits, where arithmetic circuits play important roles. In order to develop excellent SFQ arithmetic circuits, we have to design or select their underlying algorithms, called hardware algorithms, from different point of view than CMOS circuits, because ...
متن کاملsimulation and design of electronic processing circuit for restaurants e-procurement system
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
15 صفحه اولNb 9-Layer Fabrication Process for Superconducting Large-Scale SFQ Circuits and Its Process Evaluation
We describe the recent progress on a Nb nine-layer fabrication process for large-scale single flux quantum (SFQ) circuits. A device fabricated in this process is composed of an active layer including Josephson junctions (JJ) at the top, passive transmission line (PTL) layers in the middle, and a DC power layer at the bottom. We describe the process conditions and the fabrication equipment. We u...
