Paper Abstract

LWIR and Multi-color LWIR Focal Planes are being developed for a variety of Space applications. A variety of Focal Plane array technologies, that includes HgCdTe, PbSnTe and other novel technologies are being developed. These detectors FPAs will require High quality two-dimensional, small unit cell, Silicon CMOS based ROICs for efficient read-out circuits. This Paper will discuss some of the salient features of various approaches being developed for the IR focal plane applications. We will also present Trade-off analysis for design of a trans-impedance input amplifier with reset and compact signal average for low noise performance. We will also discuss the various approaches for design of an A/D converter with high linearity and speed. We will discuss approaches to achieve ROIC with low noise floor, high dynamic range and high frame rate.
