The concept of a camera system capable of simultaneous passive imaging and dynamic ranging in different regions of the detector is presented. Such an adaptive-autonomous detector with both spatial and temporal control requires programmable window of exposure (time frames), ability to switch between readout modes such as full-frame imaging and zero-suppressed data, modification of the number of pixel data bits and independent programmability for distinct detector regions. In this work, a method is presented for seamlessly changing time frames and readout modes without data corruption while still ensuring that the data acquisition system (DAQ) does not need to stop and resynchronize at each change of setting, thus avoiding significant dead time. Data throughput is maximized by using a minimum unique data format, rather than lengthy frame headers, to differentiate between consecutive frames. A data control and transmitter (DCT) synchronizes data transfer from the pixel to the periphery, reconfigures the data to transmit it serially off-chip, while providing optimized decision support based on a DAQ definable mode. Measurements on a test structure demonstrate that the DCT can operate at 1 GHz in a 65 nm LP CMOS process.<\/jats:p>","DOI":"10.3390\/s20092560","type":"journal-article","created":{"date-parts":[[2020,5,4]],"date-time":"2020-05-04T14:00:43Z","timestamp":1588600843000},"page":"2560","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Dynamically Reconfigurable Data Readout of Pixel Detectors for Automatic Synchronization with Data Acquisition Systems"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1252-1447","authenticated-orcid":false,"given":"Farah","family":"Fahim","sequence":"first","affiliation":[{"name":"ASIC Development Group, Particle Physics Division, Fermi National Accelerator Laboratory, Batavia, IL 60510, USA"},{"name":"Bio-Inspired Sensors and Optoelectronics Laboratory, Northwestern University, 2145 Sheridan Rd, Evanston, IL 60208, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3828-6513","authenticated-orcid":false,"given":"Simone","family":"Bianconi","sequence":"additional","affiliation":[{"name":"Bio-Inspired Sensors and Optoelectronics Laboratory, Northwestern University, 2145 Sheridan Rd, Evanston, IL 60208, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"Rabinowitz","sequence":"additional","affiliation":[{"name":"Bio-Inspired Sensors and Optoelectronics Laboratory, Northwestern University, 2145 Sheridan Rd, Evanston, IL 60208, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7640-4050","authenticated-orcid":false,"given":"Siddhartha","family":"Joshi","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Northwestern University, 2145 Sheridan Rd, Evanston, IL 60208, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0183-4213","authenticated-orcid":false,"given":"Hooman","family":"Mohseni","sequence":"additional","affiliation":[{"name":"Bio-Inspired Sensors and Optoelectronics Laboratory, Northwestern University, 2145 Sheridan Rd, Evanston, IL 60208, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,30]]},"reference":[{"key":"ref_1","first-page":"90","article-title":"Digital-pixel FPAs enhance infrared imaging capabilities","volume":"49","author":"Kelly","year":"2013","journal-title":"Laser Focus World"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1503","DOI":"10.1109\/TII.2016.2641462","article-title":"FPGA-based reconfigurable data acquisition system for industrial sensors","volume":"13","author":"Bao","year":"2016","journal-title":"IEEE Trans.
