But, that is for expensive, cooled, DoD application with array sizes of 0.065 Mpixels (as of 2009).

Still, there is a power issue in the continuous time preamp, and in the continuous time comparators for the pulse train generator (multiply by 12 million pixels), and it still a lot of circuitry for a 1.5um pixel or smaller. It must be nice to be a computer scientist and not have to worry about pesky practical product hardware issues...although MIT LL ought to know better.<br />On the other hand, why not just increase the counter bit depth to 20 or 30 bits, or make the converter non-linear, or a hundred other things for improving DR, if we are not worried about circuit area or power per pixel?Eric R Fossumhttps://www.blogger.com/profile/05760161812378760637noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-26802553667194194922015-08-19T09:07:47.023+03:002015-08-19T09:07:47.023+03:00Check out the work of Yadid-Pecht (conditional res...Check out the work of Yadid-Pecht (conditional reset) and Hornsey (light to frequency modulation), they did exactly the same thing as what is shown here.
