Abstract: Column signal processing units are provided in correspondence with respective columns of a pixel array. The column signal processing unit includes a sample-and-hold unit configured to hold an analog signal output from a pixel, a buffer unit configured to buffer the signal held in the sample-and-hold unit, and an AD conversion unit. The AD conversion unit converts the signal held by the sample-and-hold unit and buffered by the buffer unit into a digital signal.

Abstract: A solid-state imaging apparatus and an imaging system which can reduce the occurrence of darkening and decrease deterioration in CDS performance are provided. The solid-state imaging apparatus has: a pixel unit including a photoelectric conversion unit for generating a signal by a photoelectric conversion; an amplifier unit for amplifying the signal generated by the photoelectric conversion unit; and a limiting circuit for limiting a level of an output signal from the amplifier unit. The pixel unit outputs a noise signal under a reset state during a first period and outputs a pixel signal under a non-reset state during a second period. The limiting circuit limits the level of the output signal from the amplifier unit in the first period, lower than the level of the output signal from the amplifier unit in the second period.
