10. DESCRIPTION OF CMOS IMAGE SENSOR

10-1 THEORY OF CMOS IMAGE SENSOR

The pixel of a CMOS image sensor is composed of the photodiode and the amplifier that converts the

charge into voltage. Entered light is converted to charge and converted to voltage in the pixel. The voltage

of each pixel is output by switching the switch one by one. (Figure 10-1)

The scientific CMOS image sensor used in this camera has an on-chip CDS (correlated double sampling)

circuit, which plays an important role in achieving low noise. In addition, column amplifiers and A/Ds are

adopted for odd row pixels and even row pixels, respectively. For this reason, 2 line parallel readout is

conducted and both low noise and high speed readout are provided simultaneously.
