Abstract:
A time of flight pixel includes a photodiode that accumulates charge in response to light incident upon the photodiode. A first transfer transistor is couple between the photodiode and a first charge storage device to selectively transfer charge to the first charge storage device from the photodiode. A second transfer transistor coupled between the photodiode and a second charge storage device to selectively transfer charge to the second charge storage device from the photodiode. An enable transistor is coupled between the first charge storage device and a readout node coupled to the second charge storage device to selectively couple the first charge storage device to the readout node. An amplifier transistor having a gate is also coupled to a readout node.
