Reuters: Tower announced today that it was chosen by JPL to manufacture a CMOS image sensor for use in the development of its advanced MultiSpectral Polarimetric Imager (MSPI). The device uses an image sensor process at Tower's Fab1 facility.
This design is JPL's fifth submission to Tower, dating back to April, 2001. The previous submissions totaled 28 different designs, with this latest design being the most challenging of the series fabricated for JPL by Tower. Through its airborne and planned space-borne implementation, the MSPI is intended for the study of atmospheric aerosols.
A high-speed on-chip 50Msps ADC is 9-bit square-root-encoded, resulting in the equivalent of 14-bit quantization at low signal levels. The imager is said to have a high QE and 10e read noise.
