The new technique provides a significantly simpler and more reliable method to determine the crosstalk, compared to a more complex experimental setup with a laser source. The technique is used to characterise a novel single-chip array, fabricated on a single dielectric membrane. We propose a theoretical model to simulate the crosstalk, which shows good agreement with the experimental results. Our results allow a better understanding of the thermal effects in these devices, which are at the center of a rising market of industrial and consumer applications.<\/jats:p>","DOI":"10.3390\/s20092573","type":"journal-article","created":{"date-parts":[[2020,5,4]],"date-time":"2020-05-04T14:00:43Z","timestamp":1588600843000},"page":"2573","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Crosstalk Analysis of a CMOS Single Membrane Thermopile Detector Array"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5222-1911","authenticated-orcid":false,"given":"Ying","family":"Dai","sequence":"first","affiliation":[{"name":"Department of Engineering, University of Cambridge, Cambridge CB3 0FA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed Zeeshan","family":"Ali","sequence":"additional","affiliation":[{"name":"Flusso Limited, Cambridge CB4 0DL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Hopper","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Cambridge, Cambridge CB3 0FA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Falco","sequence":"additional","affiliation":[{"name":"Flusso Limited, Cambridge CB4 0DL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prakash","family":"Pandey","sequence":"additional","affiliation":[{"name":"Faculty of Computing, Engineering and Media, De Montfort University, Leicester LE1 9BH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chris","family":"Oxley","sequence":"additional","affiliation":[{"name":"Faculty of Computing, Engineering and Media, De Montfort University, Leicester LE1 9BH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5708-743X","authenticated-orcid":false,"given":"Daniel","family":"Popa","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Cambridge, Cambridge CB3 0FA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florin","family":"Udrea","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Cambridge, Cambridge CB3 0FA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kimata, M.
