硅跟踪器（STK）是DAMPE卫星的探测器之一，用于测量高能宇宙线的入射方向。它由6个X-Y双层硅微带探测器组成，读出通道数为73728个。在恶劣的空间环境下，如何读出通道和处理海量数据是一个巨大的挑战。1152个专用集成电路（ASIC）和384个ADC用于读出检测器通道。设计了192个跟踪器前端混合（TFH）模块和8个相同的跟踪器读出板（TRB）模块来控制和数字化前端信号。本文详细介绍了STK读出电路的设计及其性能。
The Silicon Tracker (STK) is one of the detectors of the DAMPE satellite used to measure the incidence direction of high energy cosmic rays. It consists of 6 X-Y double layers of silicon micro-strip detectors with 73728 readout channels. It is a great challenge to read out the channels and process the huge volume of data in the harsh environment of space. 1152 Application Specific Integrated Circuits (ASIC) and 384 ADCs are used to read out the detector channels. 192 Tracker Front-end Hybrid (TFH) modules and 8 identical Tracker Readout Board (TRB) modules are designed to control and digitalize the front signals. In this paper, the design of the readout electronics for the STK and its performance are presented in detail.
