“…I.C. Coherently working arrays of many junctions have therefore been used or suggested for a number of devices: (1) voltage standards (Finnegan et al, 1975;Finnegan and Wahlsten, 1978;Levinsen et al, \911\ Sullivan et al, 1979;Koyanagi et al, 1979;Kautz, 1980;Kobayashi et al, 1983); (2) parametric amplifiers (Parrish et al, 1974;Feldman et al, 1975;Chiao et al, 1976;Wahlsten et al, 1978;Rudner et al, 1979;Goodall et al, 1979;Levinsen et al, 1980) and (3) Josephson mixers (Claasen et al, 1978). A number of different fabrication techniques have been suggested in these papers.…”
