In order to support such applications, SiGe BiCMOS technology is proposed. To this end, SiGe BiCMOS devices and circuits were subject to cryogenic temperatures, total-ionizing dose (TID), and single-event effects (SEEs) to evualuate their performance for operation in space. At the transistor-level, excellent tolerance is demonstrated to TID at both room temperature and cryogenic temperature. Meanwhile, SiGe-based circuits are still sensitive to SEEs, and a radiation-hardening-by-design technique is proposed for microwave oscillators, which serve as frequency references vital to any RF system. Overall, SiGe BiCMOS should be strongly considered as a foundational technology supporting the future of commercial and scientific space applications.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Radiation Effects in SiGe BiCMOS Devices and Circuits Supporting Next-Generation Space Systems "}],"uid":"28475","created_gmt":"2023-03-31 21:28:07","changed_gmt":"2023-03-31 21:28:07","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-04-05T14:00:00-04:00","event_time_end":"2023-04-05T16:00:00-04:00","event_time_end_last":"2023-04-05T16:00:00-04:00","gmt_time_start":"2023-04-05 18:00:00","gmt_time_end":"2023-04-05 20:00:00","gmt_time_end_last":"2023-04-05 20:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room 509, TSRB","extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"192484","name":"PhD Defense, graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
