First Measurements on the Timespot1 ASIC: a Fast-Timing, High-Rate Pixel-Matrix Front-End

his work presents the first measurements performed on the timespotQ asicN as the second prototype developed for the timespot projectL the asic features a 32 × 32 channels hybridMpixel matrixN targeted to spaceMtime tracking applications in high energy physics experimentsL the system aims to achieve a time resolution of 30 ps or better at a maximum event rate of 3 MHz/channel with a data driven interfaceN power consumption can be programmed to range between 1.2 W/cm2 and 2.6 W/cm2N the presented results include a description of the asic operation and a first characterization of its performance in terms of time resolutionN
