【摘要】 为减少电路功耗和噪声,基于0.35μm n-well CMOS(Complementary Metal-Oxide Semiconductor)工艺,设计了320×240焦平面探测阵列的读出电路。该电路给出了一种新型单级电容跨导放大器,采样保持电路为相关双采样电路。电容跨导放大器采用稳定的偏置电路。该电路每帧图像的输出时间为10 ms,输出图像为100帧/s。更多还原

【Abstract】 The article designed a ROIC(Read Out Integrated Circuit) of a 320×240 FPA(Focal Plane Array)in 0.35 μm n-well CMOS(Complementary Metal-Oxide Semiconductor) process.In order to reduce power dissipation and noise,the article proposed a kind of new single-stage CTIA(Capacitive Trans-Impedance Amplifier),the sample and hold circuit use a correlated double sampling structure,the CTIA used stable bias circuit.The image output time is 10 ms/frame,therefore the output speed is 100 frame/s.更多还原
