Paper Abstract

We present in this paper a flexible Wide Dynamic Range VGA ROIC for InGaAs SWIR imaging application. The pixel design of this ROIC incorporates both the unique solar cell mode from NIT and also a source-follower (SF) based direct injection linear mode. The solarcell mode operation can cover an instantaneous dynamic range of more than 120dB in a single frame without off-chip digital NUC, while the SF mode can operation sensor in a conventional SF linear mode but with a on-chip offset compensation. The off-chip digital KTC noise cancellation is also possible in the SF mode. This ROIC has been designed and fabricated with a standard 0.18um 1P3M process, destinated to 640x512-pixel PDA of 15um pitch. The horizontal scanning speed is maximum 100MHz and 80MHz guaranteed, giving more than 150 frames per second. The overall performance of this ROIC coupled to III-VLab extended visible InGaAs PDA will be presented at the conference.
