摘要： A solid-state imaging device that suppresses streaking includes an imaging region in which unit cells are aligned in matrix, an A/D converter for converting an analog signal generated in the imaging region to a digital signal, and a ramp buffer having an input terminal and an output terminal. Ramp voltage is input to the input terminal, and a reference signal having the ramp voltage is output from the output terminal toward the A/D converter. The A/D converter includes a comparator disposed in each column for comparing an analog signal with a reference signal, and a counter disposed corresponding to the comparator for counting a comparison period of the comparator. The ramp buffer includes a feedback circuit for simultaneously outputting the reference signal to the multiple comparators and controlling the amount of current flowing to the output terminal according to the ramp voltage of the reference signal output from the terminal.
