Abstract :
This paper presents a snapshot readout integrated circuit (ROIC) for 640×512 infrared focal plane array (IRFPA) with low power and multifunction design. Based on Gray code, flexible readout modes such as dynamic image transposition and dynamic windowing readout are realized. Current is automatically adjusted according to window size to reduce power. This IRFPA ROIC is designed in 0.35μm CMOS technology.
