| 摘 要： | 为了减小CMOS图像传感器的低频噪声(如KTC噪声和1/f噪声)和固定图形噪声,采用了相关双采样技术.用标准的1.5 μm P阱双层多晶硅双层金属的CMOS数字电路工艺,研制出512像素带相关双采样的CMOS有源像素图像传感器线阵.实验结果为灵敏度11 V/Lx.s均方根噪声为0.2 mV;动态范围为80 dB,直流功耗为10 mW.

| Abstract: | This paper describes the operation principle and circuit of a CMOS act ive pixel sensors with a CorrelatedDouble Sampling ( CDS) .The CDS have been applied and proved to suppress the low frequency noise ( KTC noise and1/ f noise) and Fixed Pattern Noise( FPN) . A 512 element CMOS APS with CDS fabricated by standard 1??5??m P??wellDPDM CMOS logic process. The experimental results show that a sensitivity is 11 V/ Lx. s noise is 0??2 mV, dynamicrange is 80 dB, DC power consumption is 10 mW. |
