To solve signal-line bandwidth and fan-out problems, microwave sources required for qubit manipulation might be embedded close to the qubit chip, typically operating at temperatures below 4 K. Here, we perform the first low temperature measurements of a 130 nm BiCMOS based SiGe voltage controlled oscillator at cryogenic temperature. We determined the frequency and output power dependence on temperature and magnetic field up to 5 T and measured the temperature influence on its noise performance. The device maintains its full functionality from 300 K to 4 K. The carrier frequency at 4 K increases by 3% with respect to the carrier frequency at 300 K, and the output power at 4 K increases by 10 dB relative to the output power at 300 K. The frequency tuning range of approximately 20% remains unchanged between 300 K and 4 K. In an in-plane magnetic field of 5 T, the carrier frequency shifts by only 0.02% compared to the frequency at zero magnetic field.","lang":"eng"}],"issue":"11","oa":1,"main_file_link":[{"url":"https://arxiv.org/abs/1804.09522","open_access":"1"}],"external_id":{"isi":["000451735700054"],"arxiv":["1804.09522"]},"quality_controlled":"1","isi":1,"doi":"10.1063/1.5038258","language":[{"iso":"eng"}],"month":"11","publication_identifier":{"issn":["00346748"]},"year":"2018","publication_status":"published","publisher":"AIP Publishing","department":[{"_id":"GeKa"}],"author":[{"full_name":"Hollmann, Arne","last_name":"Hollmann","first_name":"Arne"},{"full_name":"Jirovec, Daniel","first_name":"Daniel","last_name":"Jirovec","id":"4C473F58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7197-4801"},{"first_name":"Maciej","last_name":"Kucharski","full_name":"Kucharski, Maciej"},{"full_name":"Kissinger, Dietmar","first_name":"Dietmar","last_name":"Kissinger"},{"last_name":"Fischer","first_name":"Gunter","full_name":"Fischer, Gunter"},{"full_name":"Schreiber, Lars R.","first_name":"Lars R.","last_name":"Schreiber"}],"related_material":{"record":[{"id":"10058","relation":"dissertation_contains","status":"public"}]},"date_updated":"2024-03-28T23:30:27Z","date_created":"2019-01-10T14:22:23Z","volume":89,"article_number":"114701"}]
