A major existing challenge in this area is to realize a high-performance, low-cost silicon-based integrated THz source with high spectrum purity and a wide frequency tuning range. The paper addresses this unmet need by proposing and demonstrating a novel, multi-phase sub-harmonic injection locking circuit topology, which can \u0022actively\u0022 multiply a 40 GHz signal to generate a 500 GHz signal while maintaining high DC-to-THz energy conversion efficiency and spectrum purity.\u003C\/p\u003E\u003Cp\u003ECompared with existing circuit approaches, this multi-phase sub-harmonic injection locking scheme extends the frequency tuning bandwidth by 150 percent to 200 percent under the same RF injection power. Chi\u0027s IC chip demonstrates state-of-the-art performance with a frequency tuning range of 4.4 percent and a phase noise of -77.6dBc\/Hz at 1 MHz offset among the reported fully integrated silicon-based source at 500 GHz.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EPhoto cutline:\u003C\/strong\u003E Don Thelen (left), of ON Semiconductor and the 2014 IEEE-CICC technical program chair, presents ECE Ph.D. student Taiyun Chi with the Intel\/Texas Instruments\/Catalyst Foundation Student Scholarship Award.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EECE Ph.D. student Taiyun Chi was presented with the Intel\/Texas Instruments\/Catalyst Foundation Student Scholarship Award at the 2014 IEEE Custom Integrated Circuits Conference (CICC), held September 15-17 in San Francisco.\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"ECE Ph.D. student Taiyun Chi was presented with the Intel\/Texas Instruments\/Catalyst Foundation Student Scholarship Award at the 2014 IEEE Custom Integrated Circuits Conference (CICC), held September 15-17 in San Francisco."}],"uid":"27241","created_gmt":"2014-09-19 18:16:36","changed_gmt":"2016-10-08 03:17:07","author":"Jackie Nemeth","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2014-09-29T00:00:00-04:00","iso_date":"2014-09-29T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"327621":{"id":"327621","type":"image","title":"Taiyun Chi","body":null,"created":"1449245064","gmt_created":"2015-12-04 16:04:24","changed":"1475895039","gmt_changed":"2016-10-08 02:50:39","alt":"Taiyun Chi","file":{"fid":"200260","name":"taiyun_chi_cicc_photo.jpg","image_path":"\/sites\/default\/files\/images\/taiyun_chi_cicc_photo_0.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/taiyun_chi_cicc_photo_0.jpg","mime":"image\/jpeg","size":633528,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/taiyun_chi_cicc_photo_0.jpg?itok=OiNL7Fj2"}}},"media_ids":["327621"],"related_links":[{"url":"http:\/\/www.gatech.edu\/","title":"Georgia Tech"},{"url":"http:\/\/www.ece.gatech.edu\/","title":"School of Electrical and Computer Engineering"},{"url":"http:\/\/www.ieee-cicc.org\/","title":"2014 IEEE Custom Integrated Circuits Conference (CICC)"},{"url":"http:\/\/www.ece.gatech.edu\/research\/labs\/gems\/","title":"Georgia Tech Electronics and Micro-System Lab"}],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[{"id":"134","name":"Student and Faculty"},{"id":"8862","name":"Student Research"},{"id":"145","name":"Engineering"},{"id":"149","name":"Nanotechnology and Nanoscience"},{"id":"135","name":"Research"},{"id":"150","name":"Physics and Physical Sciences"}],"keywords":[{"id":"104021","name":"2014 IEEE Custom Integrated Circuits Conference (CICC)"},{"id":"109","name":"Georgia Tech"},{"id":"104011","name":"Georgia Tech Electronics and Micro-System (GEMS) Lab"},{"id":"166855","name":"School of Electrical and Computer Engineering"}],"core_research_areas":[{"id":"39441","name":"Bioengineering and Bioscience"},{"id":"39451","name":"Electronics and Nanotechnology"}],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EJackie Nemeth\u003C\/p\u003E\u003Cp\u003ESchool of Electrical and Computer Engineering\u003C\/p\u003E\u003Cp\u003E404-894-2906\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:jackie.nemeth@ece.gatech.edu\u0022\u003Ejackie.nemeth@ece.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":["jackie.nemeth@ece.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
