Claim 13:
14. The imaging unit of claim 11, wherein the time-resolving sensor comprises a plurality of pixels, at least one pixel of the plurality of pixels comprising:
at least one single-photon avalanche diode (SPAD), each SPAD being responsive to an active shutter signal to generate an output signal based on detecting one or more photons that are incident on the SPAD and that have been reflected from the object;
a logic circuit coupled to the output signal of the at least one SPAD, the logic circuit to generate a first enable signal and a second enable signal, the first enable signal being active in response to a beginning of the active shutter signal and being inactive in response to the output signal of the at least one SPAD, and the second enable signal being in active in response to the output signal of the at least one SPAD and being inactive in response to an end of the active shutter signal; and
a differential time-to-charge converter (DTCC) circuit coupled to the first and second enable signals that outputs the first signal and the second signal.
