Light-receiving device and method for reading out signal of light-receiving device
Abstract:
A light-receiving device that achieves both high saturation performance and high sensitivity performance includes a light-receiving pixel including a light-receiving element, a first capacitive element that accumulates a photoelectric charge produced by light received by the light-receiving element, a second capacitive element that accumulates a transferred portion of an amount of the photoelectric charge accumulated in the capacitive element, a switch means for turning on and off a photoelectric charge transfer operation from the capacitive element to the capacitive element, a resetting switch means for resetting the capacitive element and the capacitive element, a pixel selecting switch means, and a source follower switch means. An effective saturation capacity of the capacitive element is 10 to 5,000 times an effective saturation capacity of the capacitive element.
