IMAGE SENSOR CONTROLLING A CONVERSION GAIN, IMAGING DEVICE HAVING THE SAME, AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18221921 titled 'IMAGE SENSOR CONTROLLING A CONVERSION GAIN, IMAGING DEVICE HAVING THE SAME, AND METHOD OF OPERATING THE SAME
Simplified Explanation
The patent application describes an image sensor with two pixels connected to a column line.
- Each pixel consists of a photodiode, two floating diffusion regions, and several transistors.
- The transistors are connected in a specific configuration to control the flow of charge in the pixel.
- The second floating diffusion region of the first pixel and the second floating diffusion region of the second pixel are directly connected without any additional transistor in between.
Original Abstract Submitted
An image sensor includes: a first pixel connected to a column line; and a second pixel connected to the column line. Each of the first pixel and the second pixel includes: one photodiode; a first floating diffusion region; a second floating diffusion region; one first transistor connected between the one photodiode and the first floating diffusion region; a second transistor connected between the first floating diffusion region and the second floating diffusion region; a third transistor connected to the second floating diffusion region; a fourth transistor including a gate connected to the first floating diffusion region; and a fifth transistor including a drain connected to a source of the fourth transistor and a source connected to the column line. The second floating diffusion region of the first pixel and the second floating diffusion region of the second pixel are electrically connected without an intermediate transistor.
