Abstract
Wide dynamic range active pixel sensor(APS) using a charge pump circuit has been designed by using 2-poly 4-metal $0.35{\mu}M$ standard CMOS technology. The structure of the proposed APS is similar to the structure of the conventional 3-Tr APS. The proposed unit pixel consists of one photodiode and three MOSFETs. Using a charge pump circuit, the dynamic range of the proposed APS is increased, compared to the conventional 3-Tr APS.
