Abstract
A 3 bit single flux quantum (SFQ) shift register based on high-T-c bic rystal Josephson junctions has been designed, fabricated, and experime ntally tested. The circuit consists of 26 bicrystal Josephson junction s and includes the shift register itself, two dc-SFQ converters, one r eadout superconducting quantum interference device, serving as a SFQ-d c converter, and three Josephson transmission lines. The correct opera tion of all circuit components has been demonstrated by low frequency testing at a temperature of 50 K. (C) 1997 American Institute of Physi cs.
