Abstract
A solid-state imaging apparatus includes a pixel circuit that outputs a pixel signal and a negative feedback circuit. The negative feedback circuit includes a sample and hold circuit (hereinafter 'SH circuit') that samples and holds the pixel signal, and a feedback amplifier that negatively feeds back, to the SH circuit, a feedback signal according to a difference between the pixel signal from the pixel circuit and an output signal from the SH circuit.
