The miniaturized MIT function is enabled through single-chip transceiver implementation. The proposed MIT transceiver utilizes a phase-locked loop (PLL) for frequency sweeping and a phase-domain sigma\u2013delta modulator with phase-band auto-tracking for a full-range fine-phase resolution. The designed transceiver is fabricated and verified to achieve the measured signal to noise and distortion ratio (SNDR) of 101.7 dB. Its system-level prototype including in-house magnetic sensor coils is manufactured and functionally verified for four different material types.<\/jats:p>","DOI":"10.3390\/s18113816","type":"journal-article","created":{"date-parts":[[2018,11,7]],"date-time":"2018-11-07T10:32:07Z","timestamp":1541586727000},"page":"3816","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Portable Phase-Domain Magnetic Induction Tomography Transceiver with Phase-Band Auto-Tracking and Frequency-Sweep Capabilities"],"prefix":"10.3390","volume":"18","author":[{"given":"Chan Sam","family":"Park","sequence":"first","affiliation":[{"name":"School of Electrical and Computer Engineering, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8024-5099","authenticated-orcid":false,"given":"Jiyun","family":"Jeon","sequence":"additional","affiliation":[{"name":"School of Mechanical, Aerospace and Nuclear Engineering, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byungjoo","family":"Oh","sequence":"additional","affiliation":[{"name":"School of Electrical and Computer Engineering, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hee Young","family":"Chae","sequence":"additional","affiliation":[{"name":"School of Electrical and Computer Engineering, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8191-2436","authenticated-orcid":false,"given":"Kyeonghwan","family":"Park","sequence":"additional","affiliation":[{"name":"School of Electrical and Computer Engineering, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hungsun","family":"Son","sequence":"additional","affiliation":[{"name":"School of Mechanical, Aerospace and Nuclear Engineering, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4581-4115","authenticated-orcid":false,"given":"Jae Joon","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Electrical and Computer Engineering, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, G., Ma, K., Sun, J., Jin, G., Qin, M., and Feng, H.
