Abstract

Thermal imaging market is today more and more attracted by systems with "instant-on" and low power consumption. Therefore the "TECless" operation of uncooled microbolometer detectors, that is where no Peltier module is needed, is the major step to fulfill the market requirement. In order to fulfill this trend, LETI/SLIR is working on a new IRCMOS architecture. This new design is based on a differential reading implemented with current mirrors that simultaneously reduces focal plane temperature sensitivity and simplifies the detector driving. An IRCMOS prototype (320 x 240 with a pitch of 25 &mgr;m) has been designed, processed, and characterized. This paper presents an overall view of this new design and the preliminary characterization results got from this focal plane array.
