The time and expense involved in producing infrared hybrid focal plane arrays (IRFPAs) dictates that optimal designs be used. The use of accurate signal and noise models, which identify the critical focal plane design parameters, are essential in obtaining these optimal designs. We describe the methodology behind building a signal and noise model for a hybrid infrared focal plane array consisting of photodetectors coupled to silicon complementary- symmetry metal-oxide-semiconductor (CMOS) readouts. The CMOS readout is essential in transducing the infrared photosignal to a usable voltage domain form, but introduces front-end noise in the hybrid FPA. A signal and noise model for a photodetector-readout combination that is currently used in many applications is examined in order to identify the parameters that affect performance.
