摘要：

我们证明并证明在这里的例子的大规模像素检测器的ATLAS的像素模块的串行供电是一个可行的替代方案，并已设计和实施的ATLAS像素模块使用专用的片上电压调节器和修改的柔性混合电路。等效的像素阶梯组成的六个串联供电的像素模块约0.3Mpixels已建成和性能方面的噪声和阈值的稳定性和操作故障进行了研究。我们相信，串行供电一般将是必要的，未来的大规模跟踪探测器。

英文摘要：

We prove and demonstrate here for the example of the large scale pixel detector of ATLAS that Serial Powering of pixel modules is a viable alternative and that has been devised and implemented for ATLAS pixel modules using dedicated on-chip voltage regulators and modified flex hybrids circuits. The equivalent of a pixel ladder consisting of six serially powered pixel modules with about 0.3Mpixels has been built and the performance with respect to noise and threshold stability and operation failures has been studied. We believe that Serial Powering in general will be necessary for future large scale tracking detectors.
