RGBZ PIXEL UNIT CELL WITH FIRST AND SECOND Z TRANSFER GATES |
摘要 |
An image sensor is described having a pixel array. The pixel array has a unit cell that includes visible light photodiodes and an infra-red photodiode. The visible light photodiodes and the infra-red photodiode are coupled to a particular column of the pixel array. The unit cell has a first capacitor coupled to the visible light photodiodes to store charge from each of the visible-light photodiodes. The unit cell has a readout circuit to provide the first capacitor's voltage on the particular column. The unit cell has a second capacitor that is coupled to the infra-red photodiode through a first transfer gate transistor to receive charge from the infra-red photodiode during a time-of-flight exposure. The first capacitor is coupled to the infra-red photodiode through a second transfer gate transistor to receive charge from the infra-red photodiode during the time-of-flight exposure. |
