粒子流算法量热法需要高粒度的三维读出。通过仅在射束传输期间启用读出ASIC电流（对应于1%的占空比），可达到40μW/通道的严格功率要求。由电流开关引起的EMI噪声需要由电源系统最小化，本文提出了最小化干扰的想法，仿真和第一次测量。精心设计的电路、印刷电路板、接地方案和浮动电源的使用允许电流回路局部闭合，稳定电压和金属结构中的最小电流。
Particle flow algorithm calorimetry requires high granularity three-dimensional readout. The tight power requirement of 40μW/channel is reached by enabling readout ASIC currents only during beam delivery, corresponding to a 1% duty cycle. EMI noise caused by current switching needs to be minimized by the power system and this paper presents ideas, simulations and first measurements for minimizing disturbances. A carefully design of circuits, printed circuit boards, grounding scheme and use of floating supplies allows current loops to be closed locally, stabilized voltages and minimal currents in the metal structures.
