需要一种诊断药片才能到达内窥镜无法接触到的胃肠道部分，并检测来自癌细胞的荧光。这种药丸的关键部件是一个非常灵敏的光探测器，它足够紧凑，可以集成到药丸中。本文描述了一种电荷泵，它可以像台式电源一样有效地偏置单光子雪崩探测器。
A diagnostic pill is required to reach parts of the gastrointestinal tract that are inaccessible to endoscopes and detect the fluorescence from cancer cells. The key component of this pill is a very sensitive light detector that is compact enough to be integrated within the pill. In this paper, a charge pump is described that can bias a single photon avalanche detector as effectively as a bench top power supply.
