英文摘要	A readout integrated circuit (ROIC) for uncooled infrared focal plane array (IRFPA) is presented in this paper. The ROIC is designed for a 384??288 detector array made of amorphous silicon microbolometers with a pixel-pitch of 35??m. A capacitive trans-impedance amplifier (CTIA) is used in each column to integrate the pixel signal. The design is tuned on a detailed theoretical analysis of the sensor signal and noise properties. The chip has been fabricated using a 0.35??m 2P4M CMOS process under 5V supply voltage. The ROIC can operate at a data rate of 7MHz, achieving a frame rate of 60Hz and the total power dissipation is less than 108m W. A 32??32 experimental chip has been tested. ? 2012 IEEE.; EI; 0
