Patent attributes
An imaging device includes: a pixel; a signal line electrically connected to the pixel; and a first and second sample-and-hold circuits electrically connected to the signal line. The pixel includes: a photoelectric converter that generates signal charge; a charge accumulation region that accumulates the signal charge; a reset transistor that resets a voltage of the charge accumulation region; and an amplifier transistor that amplifies a signal voltage. The first sample-and-hold circuit includes: a first switch that is electrically connected to the signal line and has input-output characteristics in which an output is clipped at a clipping voltage with respect to an input exceeding the clipping voltage; and a first capacitor electrically connected to the signal line through the first switch. The second sample-and-hold circuit includes: a second switch electrically connected to the signal line; and a second capacitor electrically connected to the signal line through the second switch.
