Viable mm-Wave TX front-end solutions are expected to support multi-Gbps spectrum-efficiency modulated signals, such as high-order QAMs. The corresponding large PAPRs of the high-order QAM and OFDM push the already stringent linearity-efficiency requirements on the deployed TXs\/PAs. On one hand, the TX\/PA must exhibit excellent linearity over a large dynamic range to maintain the signal fidelity. On the other hand, the TX\/PA should enhance its efficiency at PBO to minimize overall power consumption and thus alleviate thermal management. Feasible mm-Wave RX front-end solutions should achieve high sensitivity and linearity while maintaining a wide bandwidth to handle high-speed and high-order modulated signals. A low RX noise figure and the resulting high RX sensitivity are essential to compensate the high path loss at mm-Wave in wireless communication. Moreover, massive MIMO and phased array architectures are extensively utilized to improve mm-Wave link performance and spatial diversity via beamforming. A high linearity RX implementation is required to avoid decorrelations among the MIMO\/phased-array elements and mitigate intermodulation distortions during concurrent multi-beams\/streams receiving. My Ph.D. research aims to exploit new circuit architectures and techniques to address the mm-Wave transceiver design challenges.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Millimeter-Wave CMOS Transceiver Front-end Circuits for Future Energy-efficient, Linear, and Wideband Communication Systems "}],"uid":"28475","created_gmt":"2020-07-06 22:36:20","changed_gmt":"2020-07-07 13:25:34","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-07-17T11:00:00-04:00","event_time_end":"2020-07-17T13:00:00-04:00","event_time_end_last":"2020-07-17T13:00:00-04:00","gmt_time_start":"2020-07-17 15:00:00","gmt_time_end":"2020-07-17 17:00:00","gmt_time_end_last":"2020-07-17 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":""}}}
