  • SOLID-STATE IMAGING DEVICE
    Publication number: 20100289932
    Abstract: Suppressing increases in the area of an image cell while reducing fixed pattern noise (FPN). A photoelectric conversion signal is generated from photocurrent flowing through a photodiode (PD) in a pixel (Ca). A first transistor functioning as a load transistor is driven to operate in a strong inversion state and then operate in a subthreshold range. When the first transistor (T1) is operating in a subthreshold range, the potential at a sense node (N1) is read as a reset signal. Further, the difference between the photoelectric conversion signal and the reset signal is calculated to generate an image signal (Vs).
