To synchronize these SFQ oscillators, a common constant bias current is supplied to the SFQ oscillators without any bias resistors. When an SFQ oscillator oscillates at a frequency of f, the average voltage across the Josephson junction comprising the SFQ oscillator is fΦ_o, where  fΦ_o  is the flux quantum in the superconductor. The bias currents supplied to the SFQ oscillators are redistributed to eliminate the average voltage difference output from the SFQ oscillators. As a result, the oscillation frequencies of all the SFQ oscillators are synchronized. Simulation results indicate that SFQ oscillators with an oscillation frequency difference of more than 50 GHz can be synchronized. We experimentally demonstrate the frequency synchronization of two SFQ oscillators composed of circular Josephson transmission lines. Frequency synchronization is expected to contribute toward the development of a low-power stable clock source stabilizing SFQ circuit operation.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1088/1361-6668/ac1d96","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.1088/1361-6668/ac1d96"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1088/1361-6668/ac1d96","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1247275X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13616668","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Electrical and Computer Engineering, Yokohama National University & Institute of Advanced Sciences, Yokohama National University"},{"subitem_text_value":"Department of Electrical and Computer Engineering, Yokohama National University"},{"subitem_text_value":"Department of Electrical and Computer Engineering, Yokohama National University & Institute of Advanced Sciences, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yuki, Yamanashi"}],"nameIdentifiers":[{"nameIdentifier":"19078","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70467059","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70467059"}]},{"creatorNames":[{"creatorName":"Ryo, Kinoshita"}],"nameIdentifiers":[{"nameIdentifier":"40876","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobuyuki, Yoshikawa"}],"nameIdentifiers":[{"nameIdentifier":"35237","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70202398","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70202398"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-02-08"}],"displaytype":"detail","filename":"Yamanashi2021SUST.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"Yamanashi2021SUST.pdf","url":"https://ynu.repo.nii.ac.jp/record/11586/files/Yamanashi2021SUST.pdf"},"version_id":"ae0ab9d6-408f-47a2-b31f-7025143bbefa"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SFQ circuit","subitem_subject_scheme":"Other"},{"subitem_subject":"synchronization","subitem_subject_scheme":"Other"},{"subitem_subject":"clock generator","subitem_subject_scheme":"Other"},{"subitem_subject":"Josephson junction","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Frequency synchronization of single flux quantum oscillators","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Frequency synchronization of single flux quantum oscillators"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-02-08"},"publish_date":"2022-02-08","publish_status":"0","recid":"11586","relation_version_is_last":true,"title":["Frequency synchronization of single flux quantum oscillators"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T17:53:42.927106+00:00"}
