Paper Abstract

The readout integrated circuit (ROIC) for micro-bolometric infrared focal plane array (IRFPA) is commonly fabricated in silicon complementary metal oxide semiconductor field effect transistor (CMOS) technology. There are three main categories of noise in a typical CMOS ROIC, which are 1/f noise, KTC noise and fixed pattern noise. These noises in CMOS ROIC can seriously restrain the dynamic range of the ROIC and degrade the performance of IRFPA. A new CMOS ROIC for micro-bolometric IRFPA is designed to suppress the noises, and its performance is successfully verified through the theory analysis and experimental results in this paper.
