Abstract

A monolithic infrared focal plane array where photo-diodes and field effect transistors are integrated is presented. The photodiode is connected directly to the integrating capacitor while the transistor controls the integrated signal-charge transfer to the video line. The operating modes of such array are discussed and especially the pseudo-staring mode. Such arrays were produced and their system performance were investigated. The detectors average specific detectivity D^*_(lambda )(f/no equals 1, (lambda) equals 3.83 micrometers ) was equal to 1.3 X 10¹¹ [cm-Hz^1/2/W] and was used to calculate the Noise Equivalent Temperature Difference (NETD) as a function of the number of detectors and vectors. The NETD was estimated to be of 0.039 K for an optimal 5 vectors array.
