SOLID-STATE IMAGING DEVICE AND IMAGING DEVICE

摘要

This invention provides a solid-state imaging device that can capture high-quality images. Said solid-state imaging device has a plurality of unit cells that are arrayed two-dimensionally and generate pixel signals that are functions of light-reception amounts, a plurality of vertical signal lines that are provided per unit-cell column and transfer the pixel signals, a plurality of comparison circuits provided so as to correspond to the respective vertical signal lines, and a reference-signal generation circuit that supplies a shared reference signal to the comparison circuits. Each comparison circuit contains a differential amplifier circuit (200) that outputs a signal that is a function of the difference between the reference signal and a pixel signal, switching transistors (211 and 212) for eliminating the offset of the differential amplifier circuit (200), and an inverter circuit (215) connected to the control terminals of the switching transistors (211 and 212).
