双面硅带探测器在行星际探测中得到了广泛的应用。本文介绍了用于空间探索的DSSD读出电子器件的原型。主要包括前端读出模块（FEM）和数据采集模块（DAM）。基于特定应用的集成电路和极性逆变电路，FEM负责获取DSSD信号的电荷。采用带现场可编程门阵列的DAM进行位置和能量的在线计算以及数据的封装和传输。测试结果表明，电子器件的动态范围为6-2500和-6 ~ -2500 fC，积分非线性不大于0.5%，均方根噪声水平小于1.9 fC。与DSSD的联合测试表明，在5.486 MeV下实现了全宽度3.25%的半最大能量分辨率和1.19 mm的位置分辨率。
Double-sided silicon strip detectors (DSSDs) have been widely used in interplanetary exploration. In this study, the prototype readout electronics of a DSSD for space exploration is presented. It mainly includes a front-end readout module (FEM) and a data acquisition module (DAM). The FEM is responsible for acquiring the charge of the DSSD signals based on an application-specific integrated circuit and polarity inverter circuits. The DAM with a field programmable gate array is employed to perform online calculations of the position and energy as well as data packaging and transfer. Test results show that the electronics has dynamic ranges of 6-2500 and -6 to -2500 fC with an integral nonlinearity of no more than 0.5%, while the root-mean-square noise level is less than 1.9 fC. Joint tests with the DSSD indicate that a full width at half maximum energy resolution of 3.25% at 5.486 MeV and a position resolution of 1.19 mm were achieved.
