摘　　要：介绍了一种针对二氧化钒敏感材料的CMOS读出电路(RO IC).该电路结构简单,适合大规模焦平面阵列,并具有良好的低噪特性,可以有效地降低焦平面衬底温度波动影响和抑制一些低频噪声.该读出电路已成功地应用于32×32元微测辐射热计焦平面阵列原型.A complementary metal oxide semiconductor （CMOS） readout integrated circuit （ROIC） for the sensitive material of vanadium dioxide （VO2） was introduced. The ROIC is simply configurable which is adaptable to large-scale focal plane arrays, and has excellent low-noise performance, which can effectively reduce the influence of changes in the substrate temperature and depress some low-frequency noise. The readout circuit has successfully been applied for prototypes of 32 × 32 element microbolometric focal plane arrays （FPAs）.
