The efficient correlated double sampling (CDS) method in pixels is used to optimize the noise characteristics of the ROIC and output CDS voltage to the column bus. An AC enhancement method is proposed to quickly establish the column bus signal, and an adaptive offset compensation method is used at the column bus terminal to eliminate the nonlinearity caused by the pixel source follower (SF). Based on the 55 nm process, the proposed method is comprehensively verified in an 8192 \u00d7 8192 IR ROIC. The results show that, compared with the traditional readout circuit, the output swing is increased from 2 V to 3.3 V, and the full well capacity is increased from 4.3 Me- to 6 Me-. The row time of the ROIC is reduced from 20 \u00b5s to 2 \u00b5s, and the linearity is improved from 96.9% to 99.98%. The overall power consumption of the chip is 1.6 W, and the single-column power consumption of the readout optimization circuit is 33 \u03bcW in the accelerated readout mode and 16.5 \u03bcW in the nonlinear correction mode.<\/jats:p>","DOI":"10.3390\/s23125667","type":"journal-article","created":{"date-parts":[[2023,6,19]],"date-time":"2023-06-19T02:29:19Z","timestamp":1687141759000},"page":"5667","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["High-Linearity and High-Speed ROIC of Ultra-Large Array Infrared Detectors Based on Adaptive Compensation and Enhancement"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4921-3296","authenticated-orcid":false,"given":"Zhongjie","family":"Guo","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Xi\u2019an University of Technology, No. 5, Jinhua South Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Xi\u2019an University of Technology, No. 5, Jinhua South Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suiyang","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Xi\u2019an University of Technology, No. 5, Jinhua South Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruiming","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Xi\u2019an University of Technology, No. 5, Jinhua South Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ningmei","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Xi\u2019an University of Technology, No. 5, Jinhua South Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1593","DOI":"10.1002\/cta.2485","article-title":"An ultra-linear CMOS image sensor for a high-accuracy imaging system","volume":"46","author":"Teymouri","year":"2018","journal-title":"Int.
