The developed 3 \u03bcm pixel is capable of having three conversion gains. Introducing a new split-pinned photodiode structure, linear full well reaches 40 ke\u2212. Readout noise under the highest pixel gain condition is 1 e\u2212 with a low noise readout circuit. Merging two signals, one with high pixel gain and high analog gain, and the other with low pixel gain and low analog gain, a single exposure dynamic rage (SEHDR) signal is obtained. Using this technology, a 1\/2.7\u201d, 2M-pixel CMOS image sensor has been developed and characterized. The image sensor also employs an on-chip linearization function, yielding a 16-bit linear signal at 60 fps, and an intra-scene dynamic range of higher than 90 dB was successfully demonstrated. This SEHDR approach inherently mitigates the artifacts from moving objects or time-varying light sources that can appear in the multiple exposure high dynamic range (MEHDR) approach.<\/jats:p>","DOI":"10.3390\/s18010203","type":"journal-article","created":{"date-parts":[[2018,1,15]],"date-time":"2018-01-15T04:01:55Z","timestamp":1515988915000},"page":"203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["An Over 90 dB Intra-Scene Single-Exposure Dynamic Range CMOS Image Sensor Using a 3.0 \u03bcm Triple-Gain Pixel Fabricated in a Standard BSI Process"],"prefix":"10.3390","volume":"18","author":[{"given":"Isao","family":"Takayanagi","sequence":"first","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Norio","family":"Yoshimura","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Kazuya","family":"Mori","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Shinichiro","family":"Matsuo","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Shunsuke","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Hirofumi","family":"Abe","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Naoto","family":"Yasuda","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Kenichiro","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Shunsuke","family":"Okura","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Shinji","family":"Ohsawa","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]},{"given":"Toshinori","family":"Otaka","sequence":"additional","affiliation":[{"name":"Brillnics Japan Inc., 6-21-12 Minami-Oi, Shinagawa-ku, Tokyo 140-0013, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2018,1,12]]},"reference":[{"key":"ref_1","unstructured":"Komobuchi, H., Fukumoto, A., Yamada, T., Matsuda, Y., and Kuroda, T.
