Abstract :
Shift registers operated in ´xor´ feedback mode and utilized as pseudo random noise generators are very attractive for application in RF noise power metrology. The paper reports on the concept of integrated circuitry required, based on superconducting Rapid-Single-Flux-Quantum (RSFQ) logic, and realized in Nb/Al/sub 2/O/sub 3/-Al/Nb technology. Results of shift register operation are presented for clock frequencies up to 70 GHz.
