CMOS VLSI Active-Pixel Sensor for Tracking

An architecture for a proposed active pixel sensor (APS) and a design to implement the architecture in a complementary metal oxide semiconductor (CMOS) very-large-scale integrated (VLSI) circuit provide for some advanced features that are expected to be especially desirable for tracking pointlike features of stars. The architecture would also make this APS suitable for robotic-vision and general pointing and tracking applications.
