Superconducting nanowire single photon detectors (SNSPDs) , those have a low dark count rate characteristics, fast and low jitter response, and high quantum efficiency, are expected to be used in the time-resolving photon detection system. A readout circuit using superconducting single-flux-quantum (SFQ) logic circuits has been developed to realize fast and low-jitter readout for an array of SNSPDs. To enhance timing resolution, we are investigating a high-timing resolution time-to-digital converter using SFQ logic circuit based on the CONNECT cell library. Using a series array of a time-resolving dynamic AND gates, we could obtain a timing resolution less than 20 ps. We will present details of design of the time-to-digital converter, measurement results of fabricated circuits at the CRAVITY, the AIST. |
