Large-Pixel Architectures Aid Radiographic Imaging
Nov 1, 2003 — Much of the effort in CMOS image sensor development to date has focused on circuit architectures and on fabrication processes for small devices. Typical applications in this category include cell-phone camera modules, Web cameras and video camera sensors. Compared with CCD technology, the challenges of small CMOS image sensors, especially in high-volume applications, are well-documented and involve issues related to fill factor, noise performance, dark current, uniformity, image lag,...
