Versatile multichannel time-to-amplitude converter for high-speed and high-precision timing applications

Timing measurements triggered by photo-detection are widely used in several different fields, such as Time-Correlated Single Photon Counting (TCSPC), Quantum Key Distribution (QKD) or Light Detection and Ranging (LiDAR) systems. All these applications have in common one essential element, i.e. the timing electronics, which aims at measuring the time interval between two instants and whose requirements strictly depend on the application-specific goal. In this work, we present a versatile and fully-integrated timing chip hosting eight high-performance Time-to-Amplitude Converters (TACs) integrated with a smart logic, providing to the end user a unique flexibility to select the most suitable configuration for its specific requirements.
