ATLAS内部跟踪器的高亮度升级对硅条探测器模块的供电系统提出了苛刻的要求，因为与现有的半导体跟踪器相比，通道数增加了10倍。因此，必须制定新的供电方案。目前，正在开发两种可能的方法，使用DC-DC转换技术的串行供电和并行供电方案。本文介绍了两个开关电容DC-DC转换器设计的130纳米技术。对于优化的降压转换器，预见的并行供电方案，已实现97%的功率效率，而对于电荷泵，设计的串行供电方案，已实现85%的功率效率。
The High Luminosity Upgrade of the ATLAS Inner Tracker puts demanding requirements on the powering system of the silicon strip detector modules due to 10-fold increase of the channel count compared to the existing SemiConductor Tracker. Therefore, new solutions for the powering scheme must be elaborated. Currently two possible approaches, the serial powering and the parallel powering scheme using the DC-DC conversion technique, are under development. This paper describes two switched capacitor DC-DC converters designed in a 130 nm technology. For the optimized step-down converter, foreseen for the parallel powering scheme, power efficiency of 97% has been achieved, while for the charge pump, designed for the serial powering scheme, power efficiency of 85% has been achieved.
