Unit pixel for accurately removing reset noise, solid-state image sensing device, and method for summing unit pixel signals
Abstract:
A unit pixel has a light receiving device containing a photoelectric conversion element for detecting a light to generate photoelectrons. The light receiving device contains a plurality of photoelectron distributors, which each have a first transfer unit for transferring the photoelectrons generated in the photoelectric conversion element, a photoelectron hold unit for temporarily holding the photoelectrons generated in the photoelectric conversion element, a second transfer unit for transferring the photoelectrons held in the photoelectron hold unit, and a floating diffusion layer for storing the transferred photoelectrons and converting the photoelectrons to a voltage. The unit pixel contains a reset transistor for resetting the potential of the floating diffusion layer to a reference potential and a photoelectron discharger for discharging the photoelectrons generated in the photoelectric conversion element.
Abstract(Chinese):

单位像素具有包含用于检测光以产生光电子的光电转换元件的光接收装置。 光接收装置包括多个光电子分配器，每个光电子分配器具有用于转移在光电转换元件中产生的光电子的第一转移单元，用于临时保持在光电转换元件中产生的光电子的光电子保持单元，用于 转移保持在光电子保持单元中的光电子，以及用于存储转移的光电子并将光电子转换成电压的浮动扩散层。 单位像素包含用于将浮动扩散层的电位复位为参考电位的复位晶体管和用于放电在光电转换元件中产生的光电子的光电子放电器。
