The Japanese Experiment Module (JEM) Extreme Universe Space Observatory\n(EUSO) will be launched and attached to the Japanese module of the\nInternational Space Station (ISS). Its aim is to observe UV photon tracks\nproduced by ultra-high energy cosmic rays developing in the atmosphere and\nproducing extensive air showers.\n The key element of the instrument is a very wide-field, very fast,\nlarge-lense telescope that can detect extreme energy particles with energy\nabove 1019 eV. The Atmospheric Monitoring System (AMS), comprising, among\nothers, the Infrared Camera (IRCAM), which is the Spanish contribution, plays a\nfundamental role in the understanding of the atmospheric conditions in the\nField of View (FoV) of the telescope. It is used to detect the temperature of\nclouds and to obtain the cloud coverage and cloud top altitude during the\nobservation period of the JEM-EUSO main instrument. SENER is responsible for\nthe preliminary design of the Front End Electronics (FEE) of the Infrared\nCamera, based on an uncooled microbolometer, and the manufacturing and\nverification of the prototype model. This paper describes the flight design\ndrivers and key factors to achieve the target features, namely, detector\nbiasing with electrical noise better than 100 \μV from 1 Hz to 10 MHz,\ntemperature control of the microbolometer, from 10\∘C to 40\∘C\nwith stability better than 10 mK over 4.8 hours, low noise high bandwidth\namplifier adaptation of the microbolometer output to differential input before\nanalog to digital conversion, housekeeping generation, microbolometer control,\nand image accumulation for noise reduction.\n
