A fourth-order resonator is designed using a transformer with a distributed inductor for wideband operating of the ILFD. The CR core is employed to reduce the power consumption compared to conventional cross-coupled pair ILFDs. The targeted input center frequency is 24 GHz for radar application. The self-oscillated frequency of the proposed CR-ILFD is 14.08 GHz. The input frequency locking range is from 18.8 to 33.8 GHz (57%) at an injection power of 0 dBm without a capacitor bank or varactors. The proposed CR-ILFD consumes 2.26 mW of power from a 1 V supply voltage. The entire die size is 0.75 mm \u00d7 0.45 mm. This CR-ILFD is implemented in a 65 nm complementary metal-oxide semiconductor (CMOS) technology.<\/jats:p>","DOI":"10.3390\/s21072551","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T06:05:43Z","timestamp":1617689143000},"page":"2551","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["An 18.8\u201333.9 GHz, 2.26 mW Current-Reuse Injection-Locked Frequency Divider for Radar Sensor Applications"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2059-565X","authenticated-orcid":false,"given":"Kwang-Il","family":"Oh","sequence":"first","affiliation":[{"name":"Microwave Embedded Circuit &amp; System (MECAS) Lab., School of Electrical Engineering, Chung-Ang University, 84 Heukseok, Dongjack, Seoul 06974, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Goo-Han","family":"Ko","sequence":"additional","affiliation":[{"name":"Microwave Embedded Circuit &amp; System (MECAS) Lab., School of Electrical Engineering, Chung-Ang University, 84 Heukseok, Dongjack, Seoul 06974, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong-Geun","family":"Kim","sequence":"additional","affiliation":[{"name":"Integrated Radar Lab., Department of Electronic Engineering, KwangWoon University, 20 Gwangun, Nowon, Seoul 01897, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0675-1115","authenticated-orcid":false,"given":"Donghyun","family":"Baek","sequence":"additional","affiliation":[{"name":"Microwave Embedded Circuit &amp; System (MECAS) Lab., School of Electrical Engineering, Chung-Ang University, 84 Heukseok, Dongjack, Seoul 06974, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kim, K.-R., and Kim, J.-H.
