Paper Abstract

JPL has implemented advances in CMOS APS visible sensors well suited for the development of ultra-low power, miniature, highly integrated image sensor systems. Applications for these low cost, modular, high performance 'camera-on-a-chip' sensors include: remote earth and planetary visible science cameras, wireless payload deployment monitors for large mirrors, solar panels, booms and antennas, and FPAs for star trackers, sun sensors and high bandwidth multi-window optical communication beacon tracker. This paper reports on the newest generation of CMOS APS dubbed the Versatile Integrated Digital Imager or VIDI APS 'camera-on-a-chip.' VIDI is an integrated, digital 'chip-camera' with a 512 X 512 format, 12-um pixels, utilizing a single 3.3 V supply, with analog or 10-bit digital output, fabricated on a standard 0.5 um CMOS process. The chip size is 10 mm X 15.5 mm. Features include a simple, all digital 'five-wire' interface, on-chip timing, control, four five-bit DACs for bias generation, and 512 column parallel ADCs, VIDI offers programmable exposure, resolution, data efficient 'smart' area-of-interest windowed high speed readout, no blooming, while continuing to operate with approximately 20 mW of power in the on-state and approximately 40 uW in the 'sleep' state and has a maximum data rate of 20 Mbits/sec.
