A novel kind of high-speed CMOS readout integrated circuit for large-scale microbolometric focal plane array is proposed in this paper. The proposed readout integrated circuit can directly amplify the voltage signals of all microbolometric pixels in focal plane array response to infrared irradiation and then output the amplified voltage signals column by column and row by row. Because there is no need of photo-generated current integration capacitor for microbolometric voltage response, the readout integrated circuit can save a lot of readout c...
