Its linearity is also of paramount importance to ensure the signal fidelity. Moreover, its broadband operation is highly desired for high-speed wireless communication. However, integrating a PA in silicon entails challenges due to the PA\u0026rsquo;s nature of large-signal and highly dynamic operation. This research exploits the mixed-signal computation and novel on-chip electromagnetic networks to enable intelligent RF\/millimeter-wave large-signal operation in silicon. This research demonstrates the introduced design methodologies by silicon implementations. In a multiband millimeter-wave PA in silicon, mixed-signal reconfiguration and a novel on-chip power combiner enable broadband operation for fifth-generation (5G) communication. In a digital Doherty PA in silicon, flexible and precise digital control optimizes in-field Doherty efficiency enhancement and enables robustness against antenna mismatch. In addition, this research demonstrates two hybrid PA efficiency enhancement techniques that leverage digital-intensive architectures in silicon. Mixed-signal linearization is introduced in these architectures to eliminate the trade-off between efficiency and linearity.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Silicon-based RF\/mm-wave Power Amplifiers and Transmitters for Future Energy-efficient and Broadband Communication Systems"}],"uid":"28475","created_gmt":"2017-03-14 21:13:03","changed_gmt":"2017-03-20 20:26:09","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-03-30T11:00:00-04:00","event_time_end":"2017-03-30T13:00:00-04:00","event_time_end_last":"2017-03-30T13:00:00-04:00","gmt_time_start":"2017-03-30 15:00:00","gmt_time_end":"2017-03-30 17:00:00","gmt_time_end_last":"2017-03-30 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"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":""}}}
