Abstract
Image sensors may include pixel circuitry to enable per-pixel integration time and read-out control. Two transistors may be coupled in series for per-pixel control, with one of the transistors being controlled on a row-by-row basis and the other transistor being controlled on a column-by-column basis. The two transistors in series may be coupled directly to each other without any intervening structures. Two transistors in series between a photodiode and a power supply terminal enables per-pixel control of starting an integration time, two transistors in series between a photodiode and a charge storage region enables per-pixel control of ending an integration time, and two transistors in series between a charge storage region and a floating diffusion region enables per-pixel control of read-out.
