一种用于非制冷红外焦平面阵列的低噪声高均匀性读出电路
A low noise and high uniformity readout integrated circuit for IFPA applications
摘要
Abstract
This paper proposed a readout integrated circuit ( ROIC) with high uniformity and low-noise, by mitiga-ting the fixed patter noise ( FPN) of Infrared focal plane arrays ( IFPA) to acquire high-quality infrared images. The row shared gain-controlling NMOS transistors are adopted in front-end circuit to reduce the pixel FPN.Further-more, a novel correlated double sampling ( CDS) structure is proposed to reduce the column FPN.Based on the simulation results, a 16 ×16 experimental chip has been manufactured adopting AMS 0.35 μm CMOS process. Extensive experiments have been implemented to verify the function and performance of the proposed readout cir-cuit.The test results demonstrate the ROIC with the inherent advantages of low FPN and high uniformity, which makes it suitable for the application of high performance IFPA.关键词
