Abstract

For the Phase-II upgrade of the ATLAS Muon Spectrometer to High-Luminosity LHC, new front-end readout electronics for the Monitored Drift Tube chambers is required, as the old one no longer meets the demands. The first stage in the Monitored Drift Tubes readout chain is the Amplifier-Shaper-Discriminator chip. For the upgrade, the new ASD2 ASIC chip in IBM 130 nm CMOS technology has been developed. For the ATLAS experiment, 80000 ASD2 chips are produced, which have to be tested before integration in order to obtain the required 50000 well-performing chips in the end. Using a prototype tester board and pre-production ASD2 chips, the overall performance and the influence on programmable parameters is investigated. Based on these results, 1775 production chips are tested to define final optimized cut values for the automated production testing of all chips in the company.

用于 HL-LHC ATLAS MDT 室第二阶段升级的新型 ASD2 芯片的测试结果

为了将 ATLAS μ介子谱仪第二阶段升级为高亮度大型强子对撞机，需要为监测漂移管室安装新的前端读出电子设备，因为旧的设备已经不能满足要求。监测漂移管读出链的第一级是放大器-整形器-鉴别器芯片。为了进行升级，已经开发出采用 IBM 130 nm CMOS 技术的新型 ASD2 ASIC 芯片。ATLAS 实验需要生产 80000 个 ASD2 芯片，在集成前必须对这些芯片进行测试，以便最终获得所需的 50000 个性能良好的芯片。利用原型测试板和试生产的 ASD2 芯片，研究了其整体性能和对可编程参数的影响。根据这些结果，对 1775 个生产芯片进行了测试，为公司所有芯片的自动化生产测试确定了最终优化切割值。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
