Pixel of image sensor using high-speed charge transfer
A pixel of an image sensor, which is capable of resolving a depth error occurring in high-speed charge transfer, includes a detector including a plurality of doped regions configured to receive light and transfer generated electrons; and a demodulator configured to receive the electrons from the detector through a plurality of transfer gates and demodulate the electrons, wherein a first doped region from among the plurality of doped regions is doped to have a first pinning voltage, and a second doped region from among the plurality of doped regions is located adjacent to the first doped region and doped to have a second pinning voltage higher than the first pinning voltage, wherein the plurality of transfer gates is located adjacent to the second doped region.
