在本文中，我们讨论的设计，设计问题，制造和性能的2048 × 2048有源像素图像传感器在0.5微米标准CMOS工艺。每个像素，7.5 × 7.5 μ m（2），由三个晶体管和一个光电二极管，导致在1200万个晶体管芯片与16.3 × 16.5毫米的芯片尺寸。像素有一个非集成直接读出架构，与对数光电压转换。这允许数组在空间和时间上完全随机访问。该传感器有八个模拟输出，每个输出的像素速率为4.5 MHz，这意味着最大帧速率为每秒八个完整帧。子采样或窗口化可以重新获得更高的帧速率。如果接受少量的坏像素，则感官的产量高。
In this paper, ave discuss the design, design issues, fabrication, and performance of a 2048 x 2048 active pixel image sensor in a 0.5-mu m standard CMOS process. Each pixel, 7.5 x 7.5 mu m(2), consist of three transistors and a photo diode, resulting in a 12-million transistor chip with a die size of 16.3 x 16.5 mm. The pixel has a nonintegrating direct readout architecture, with a logarithmic light-to-voltage conversion. This allows the array to he fully random accessible, both in space and time. The sensor has eight analog outputs, each with a pixel rate of 4.5 MHz, which implies a maximum frame rate of eight full frames per second. Sub-sampling or windowing retakes higher frame rates possible. The yield of the senses is high if one accepts a small number of bad pixels.
