Masamitsu Tanaka,Takeshi Kondo,N. Nakajima,T. Kawamoto,Yuki Yamanashi,Y. Kamiya,A. Akimoto,Akira Fujimaki,Hisao Hayakawa,Nobuyuki Yoshikawa,Hirotaka Terai,Yoshihito Hashimoto,Shinichi Yorozu +12 more
TL;DR: An 8-bit microprocessor using passive transmission lines based on single-flux-quantum LSI technology and the design flexibility of the floor plan was enhanced and the performance of the microprocessor was improved by 20% compared with the previous design.
Journal ArticleDOI
A design approach to passive interconnects for single flux quantum logic circuits
TL;DR: In this article, an approach for interface circuits to connect Single Flux Quantum (SFQ) cells by using passive transmission lines (PTL's) was developed. But the key point is the use of approximately the same interface circuit with every SFQ cell to maintain the matching condition between the interface circuit and the PTL's.
Journal ArticleDOI
A New Design Methodology for Single-Flux-Quantum (SFQ) Logic Circuits Using Passive-Transmission-Line (PTL) Wiring
TL;DR: In this article, the authors proposed a new methodology for designing large-scale SFQ circuits using passive-transmission-line (PTL) wiring, which can drastically change the style of designing SFQ logic circuits.
