Imaging device and camera system
Abstract:
An imaging device includes: a semiconductor substrate; pixels arranged thereon; and a signal line through which a signal from a pixel is transferred. the pixel includes a photoelectric converter generating a charge, a region accumulating the charge, an amplification transistor having a gate electrically connected to the region, a first capacitor having a first terminal electrically connected to the region and a second terminal, a second capacitor having a third terminal electrically connected to the second terminal and a fourth terminal supplied with a voltage, a feedback transistor a source or a drain of which is electrically connected to the second terminal, and a feedback circuit forming a path through which an output from the amplification transistor is negatively fed back to the region. A part, which is from the feedback transistor to the first capacitor, of the path is closer to the semiconductor substrate than the signal line is.
