Abstract:In this paper, a complementary metal oxide semiconductor (CMOS) binary image sensor based on a gate/body-tied (GBT) MOSFET-type photodetector is proposed. The proposed CMOS binary image sensor was simulated and measured using a standard CMOS 0.18-μm process. The GBT MOSFET-type photodetector is composed of a floating gate (n+-polysilicon) tied to the body (n-well) of the p-type MOSFET. The size of the active pixel sensor (APS) using GBT photodetector is smaller than that of APS using the photodiode. This means… Show more
