Classification: CPC nan | IPC G  H

Claim 14:
15. The imaging unit of claim 14, wherein the DTCC circuit comprises:
a capacitive device having a first terminal and a second terminal, the second terminal being coupled to a ground voltage;
a first switching device having first, second and third terminals, the first terminal of the first switching device being coupled to the first terminal of the capacitive device, the second terminal of the first switching device being coupled to a first floating diffusion, and the third terminal of the first switching device being coupled to the first enable signal, the first switching device being responsive to the first enable signal to transfer a first charge on the capacitive device to the first floating diffusion; and
a second switching device having first, second and third terminals, the first terminal of the second switching device being coupled to the first terminal of the capacitive device, the second terminal of the second switching device being coupled to a second floating diffusion, and the third terminal of the second switching device being coupled to the second enable signal, the second switching device being responsive to the second enable signal to transfer a remaining charge on the capacitive device to the second floating diffusion,
wherein the first signal comprises a first voltage that is based on the first charge on the first floating diffusion and the second signal comprises a second voltage that is based on the remaining charge on the second floating diffusion,
wherein a drive signal that changes according to a ramp function begins to change in response to a beginning time of a first light pulse from which the one or more photons are detected to the end of the active shutter signal, the drive signal being connected to the third terminal of the first switching device if the first enable signal is active and being connected to the third terminal of the second switching device if the second enable signal is active.
