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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time-resolving sensor using SPAD + PPD or capacitors in pixel for range measurement","description":"A time-resolving sensor includes a single-photon avalanche diode (SPAD), a logic circuit and differential time-to-charge converter (DTCC) circuit.
