    摘要： An image sensor having different bias voltages is provided. The image sensor may include a plurality of pixels configured to output pixel signals based on a received optical signal, and logic circuits configured to output the pixels signals as image data. The pixels may be formed on a first region of a semiconductor substrate, the first region being substrate biased to a first voltage. The logic circuits may be formed on a second region of the semiconductor substrate different from the first region, the second region being substrate biased to a second voltage different from the first voltage. A full-well capacitance (FWC) of the photodiode may be increased by applying the first voltage, which is a negative (−) voltage, to a photodiode of a pixel to reduce (or, alternatively prevent) a blooming effect.

    摘要： An image sensor is provided including a pixel array, a correlated double sampling (CDS) unit, an analog-digital converting (ADC) unit, a control unit, and an overflow power voltage control unit. The pixel array includes at least one unit pixel that generates accumulated charges corresponding to incident light in a photoelectric conversion period and outputs an analog signal based on the accumulated charges in a readout period. The CDS unit generates an image signal by performing a CDS operation on the analog signal. An ADC unit converts the image signal into a digital signal. A control unit controls the pixel array, the CDS unit, and the ADC unit. An overflow power voltage control unit controls an overflow power voltage to have a low voltage level in the photoelectric conversion period and controls the overflow power voltage to have a high voltage level in the readout period.
