Abstract
A solid-state imaging device includes a plurality of pixels, a reference signal supply unit configured to output a reference signal, and a comparison unit configured to output a signal depending on the reference signal and a signal from the pixel. The comparison unit includes a comparator circuit including an input terminal and an output terminal, a first switch configured to connect the input terminal and the output terminal of the comparator circuit, a clamp capacitor including a first terminal connected to the input terminal of the comparator circuit, a second switch connected to a second terminal of the clamp capacitor, and configured to select one of the signal from the pixel and the reference signal and to input the selected signal to the second terminal, and a clipping circuit arranged in an electrical path through which the reference signal is input to the comparator circuit.
