Methods for improving sensitivity of CMOS active pixel sensors

摘要: The present invention relates to a CMOS active pixel sensor which includes compensation circuit capable of compensating lowered voltage output due leakage current photodiode. having light sensing unit for generating an when is incident thereupon, the amount before incidence light. A reset resets initial in response signal. sense transistor has source, drain coupled power source voltage, and gate unit. select connected transistor, provides bit line, supplies corresponding by current.
