font-size: small;\">One very interesting detail from Neale\u2019s presentation : he showed a very nice graph of published noise data which I include here in this blog (with permission of Neale !).\u00a0 On the vertical axis the input referred read noise in electrons is shown versus the conversion gain of the pixels.<\/span><\/p>\n<p><a href=\"http:\/\/harvestimaging.com\/blog\/wp-content\/uploads\/2016\/02\/160209_blog_1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-1543\" title=\"160209_blog_1\" src=\"http:\/\/harvestimaging.com\/blog\/wp-content\/uploads\/2016\/02\/160209_blog_1-300x188.jpg\" alt=\"\" width=\"300\" height=\"188\" srcset=\"https:\/\/harvestimaging.com\/blog\/wp-content\/uploads\/2016\/02\/160209_blog_1-300x188.jpg 300w, https:\/\/harvestimaging.com\/blog\/wp-content\/uploads\/2016\/02\/160209_blog_1.jpg 872w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><span style=\"font-family: Calibri; font-size: small;\">The three lines shown in the graph are lines of equal read noise, \u201cequinoise\u201d lines, but this time noise expressed in uV.\u00a0 As can be seen, the lowest noise ever reported was 0.22 electrons, presented in JEDS2015, but the lowest noise ever reported in the voltage domain was 30 uV, presented at ISSCC2012.\u00a0 I do know that expressing noise in equivalent number of electrons is a very common technique which I support as well, but nevertheless, looking to the noise in the good, old classical way gives a complete other image.\u00a0 Now the challenge is to keep the 30 uV of noise level alive, while increasing the conversion gain !<\/span><\/p>\n<p><span style=\"font-family: Calibri;
