NIT Announces InGaAs WDR Sensors
New Imaging Technology introduces the WDR InGaAs products family, including sensors and camera modules. NIT SWIR products are based on a Wide Dynamic Range ROIC and offer DR of more than 140dB in a single image. The internal Fixed Pattern Noise correction gives a high uniformity pictures in all light conditions with no need of Look-up table.

How is the PD array integrated with circuitry? it should still be silicon CMOS .. and what sort of transistors due they use in the array?
ReplyDeleteWait a minute guy, this is InGaAs. Detector is hybridized with a readout chip.
ReplyDeleteIf 140dB is true, then this is a killer product in Infrared. How do they achieve this? By just improving on fixed non-uniformity or also using some Logarithimic concepts? Are there any papers out there?
ReplyDeleteWho are their detector partners? The Taiwanese?
ReplyDelete3-5lab (sofradir) may be.
DeleteInGaAs Sofradir is being killed by SCD. They have no roadmap and no plan.
DeleteThe Taiwanese don't have a compound semi program...
ReplyDeleteOh Anon. You look like a CMOS world guy. I am talking about a small Taiwanese fab dealing only with III-V devices. Those who are in this business know what I mean.
DeleteFab is not a problem. Even in China, there are more than 1000 Fab capable to do such devices. But the key issue is in the design, how you design them and do you own IPs to protect what you do. You can search with google, you can find a lot of III-V Fab, even in Europe and in US. No secret, you can talk very openly, guy!!
Delete1000 Fabs, wow!! China must be selling SWIR products all over the world. Is that the case? I work with a SWIR leader, and I know what is status in China.
Deleteplease read carefully: it was written "capable to do". I think that it refers to III-V products related Fab such LED, laser, RF, etc. If you put all these Fab, large or small, then there should be 1000. Who is leader in SWIR actually please?
