这项工作提出了8通道FastIC ASIC开发的CMOS 65 nm技术，适用于读出的正，负极性传感器在高能物理实验，切伦科夫探测器和飞行时间系统。前端可以配置为在区分之前执行最多4个单端通道的模拟求和，以便在分割SiPM时提高时间分辨率。输出对到达时间信息和线性能量测量进行编码，后者可捕获5 µA-25 mA输入峰值电流范围内输入信号的峰值幅度。ASIC的功耗为12 mW/ch（默认设置）。用红光激光源和HPK SiPM S13360- 3050 CS测量单光子时间分辨率为140 ps FWHM。
This work presents the 8-channel FastIC ASIC developed in CMOS 65 nm technology suitable for the readout of positive and negative polarity sensors in high energy physics experiments, Cherenkov detectors and time-of-flight systems. The front-end can be configured to perform analog summation of up to 4 single-ended channels before discrimination in view of improving time resolution when segmenting a SiPM. The outputs encode the time-of-arrival information and linear energy measurement which captures the peak amplitude of the input signal in the 5 µA–25 mA input peak current range. Power consumption of the ASIC is 12 mW/ch with default settings. Measurements of single photon time resolution with a red-light laser source and a HPK SiPM S13360-3050CS are ≈140 ps FWHM.
