ABSTRACT:
An image sensor comprises an array of photodiodes and corresponding transfer cells for receiving charge packets from the photodiodes. Each of the transfer cells includes first, second and third electrodes arranged in sequence along a semiconductor channel, wherein the first and third electrodes have substantially equal time constants, and the second electrode has a lower electrical resistance than the first and third electrodes. With the charge packets being transferred to the transfer cells, first and second pulse sequences are respectively applied to the first and third electrode, of each transfer cell, and a constant potential is applied to the second electrode, wherein the first and second pulse sequences have a 90-degree phase difference with respect to each other.
