Abstract:
1. A solid-state imaging apparatus comprising: a plurality of pixels arranged along rows and columns; and a plurality of read out channels, each arranged correspondingly to one of the columns, for reading out a signal from the plurality of pixels, and a plurality of switches each corresponding to a respective one of the plurality of read out channels, for reading out the signal from each of the plurality of read out channels to a common output node; wherein each of the plurality of read out channels includes: a correlation double sampling circuit for receiving the signal read out from the plurality of pixels and reducing a noise contained in the signal; an amplifier for amplifying the signal of which noise is reduced by the correlated double sampling circuit; and an offset removing unit which includes a clamp unit, the offset removing unit for subjecting a signal outputted through the amplifier to an offset correction processing.
