| Abstract: | Infrared focal plane array column level digitization technology is a kind of analog signal through the column level digitizing technology to finally realize the digital signal output of readout integrated circuit,not only has a good anti interference ability to external noise,but also can effectively avoid the non linearity of the external electronic circuit.Because of its excellent performance,column level digitization technology is becoming an important development direction of infrared focal plane digitization technology due to the limitation of image area.This paper mainly introduces the mainstream column level digitization technology. |
