摘要:
研究适用于下一代国际线性电子对撞机中顶点探测器的CMOS有源集成像素传感器.实验芯片现采用标准 0.35 μm CMOS 工艺设计,像素矩阵为128行×32列,像素大小为25 μm×25 μm,在像素内部实现相关双次采样技术.通过采用放射源55Fe测定, 芯片等效输入随机噪声为12个电子,而固定噪声为3个电子.传感器的电荷-电压转换系数达59 μV/e-.在170 MHz工作主频下,芯片信号处理速度达12 μs/帧.芯片模拟部分功耗小于30 mW.
Abstract:
The future international linear collider (ILC) requires a vertex detector with higher spatial resolution and faster readout speed.As a potential equipment,monolithic active pixel sensor(MAPS) based on standard CMOS technology is discussed.A 128×32 pixels prototype was developed on a standard CMOS 0.35 μm process.The pitch of pixel is 25×25 μm2.Correlated double sampling (CDS) and signal amplification have been realized inside pixel.The prototype was calibrated by using a 55Fe X-ray source.For temporal noise,the input referred value is only 12 e-.For fixed pattern noise (FPN),the corresponding value is only around 3 e-.The charge-to-voltage conversion factor achieves 59 μV/e- and the readout speed reaches 12 μs/frame when the main working frequency is set to 170 MHz.The power dissipation of the whole analog part for the prototype is less than 30 mW.
