Abstract:
A time-resolving sensor includes a single-photon avalanche diode (SPAD), a logic circuit and differential time-to-charge converter (DTCC) circuit. The SPAD is responsive to a shutter signal to generate an output signal based on detecting an incident photon. The logic circuit generates first and second enable signals. The DTCC includes a capacitor device, first and second switching devices, and an output circuit. The first switching device is responsive to the first enable signal to transfer a charge on the capacitor device to the first floating diffusion. The second switching device is responsive to the second enable signal to transfer a remaining charge on the capacitor device to the second floating diffusion. The output circuit outputs a first voltage that is based on the first charge on the first floating diffusion and a second voltage that is based on the second charge on the second floating diffusion.

Claim (Index 2):
The time-resolving sensor of  claim 1 , further comprising a drive signal that changes according to a ramp function, the drive signal beginning to change in response to a beginning time of a 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.
