However, conventional ambient light sensors are large in area and small in dynamic range, and they do not take into account the effects caused due to a dark current. To address the above problems, a programmable ambient light sensor with dark current compensation and a wide dynamic range is proposed in this paper. The proposed ambient light sensor exhibits a low current power consumption of only 7.7 \u00b5A in dark environments, and it operates across a wide voltage range (2\u20135 V) and temperature range (\u221240\u201380 \u00b0C). It senses ambient light and provides an output current proportional to the ambient light intensity, with built-in dark current compensation to effectively suppress the effects of a dark current. It provides a wide dynamic range over the entire operating temperature range with three selectable output-current gain modes. The proposed ambient light sensor was designed and fabricated using a 0.18 \u00b5m standard CMOS process, and the effective area of the chip is 663 \u00b5m \u00d7 652 \u00b5m. The effectiveness of the circuit was verified through testing, making it highly suitable for portable electronic products and fluorescent fiber-optic temperature sensors.<\/jats:p>","DOI":"10.3390\/s24113396","type":"journal-article","created":{"date-parts":[[2024,5,24]],"date-time":"2024-05-24T11:17:52Z","timestamp":1716549472000},"page":"3396","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Programmable Ambient Light Sensor with Dark Current Compensation and Wide Dynamic Range"],"prefix":"10.3390","volume":"24","author":[{"given":"Nianbo","family":"Shi","sequence":"first","affiliation":[{"name":"School of Physics and Electronics, Hunan Normal University, Changsha 410081, China"},{"name":"Key Laboratory of Physics and Devices in Post-Moore Era, College of Hunan Province, Changsha 410081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Physics and Electronics, Hunan Normal University, Changsha 410081, China"},{"name":"Key Laboratory of Physics and Devices in Post-Moore Era, College of Hunan Province, Changsha 410081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhixiang","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Physics and Electronics, Hunan Normal University, Changsha 410081, China"},{"name":"Key Laboratory of Physics and Devices in Post-Moore Era, College of Hunan Province, Changsha 410081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangliang","family":"Jin","sequence":"additional","affiliation":[{"name":"School of Physics and Electronics, Hunan Normal University, Changsha 410081, China"},{"name":"Key Laboratory of Physics and Devices in Post-Moore Era, College of Hunan Province, Changsha 410081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1016\/j.trac.2018.11.014","article-title":"Point of care sensing and biosensing using ambient light sensor of smartphone: Critical review","volume":"110","author":"Dutta","year":"2019","journal-title":"TrAC Trends Anal.
