Miniaturized design for drive circuits of 320*240 uncooled infrared focal plane array

摘要

Un-cooled infrared focal plane array (FPA) has been developed sufficiently in recent years. The performance of drive circuit influence on FPA抯 characteristic directly. Based on the construct introduce of 320*240 microbolometer un-cooled focal plane array (UFPA), the analysis and description of system design for drive circuit of UFPA is emphasized. The XC9500 series products are adapted in this design, which have some virtues such as high integrative degree, high precision, lower cost and simple layout. At last, the output timing sequence of drive circuit is presented, which indicate that the drive circuit is satisfied the miniaturized requirement and has well performance.
