SUPERCONDUCTING INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To transmit a single-flux quantum pulse in a low DC current. SOLUTION: The circuit comprises multiple stages of superconducting quantum interference devices (SQUIDs); a current source 10 for providing DC current to the devices; a capacitor 19, connected between the output of a SQUID and an input of a SQUID in a subsequent stage for coupling a single-flux quantum pulse; and a capacitor 25, connected between a common terminal of a SQUID and a common terminal of a SQUID in a subsequent stage for coupling the terminals in AC current and separating them in the manner of DC current.
