KLauS是一种专用集成电路（ASIC），用于0.35 μ m SiGe技术开发的硅光电倍增管（SiPM）的读出。它的设计目的是提供高动态范围的SiPM信号的高精度电荷测量。此外，还实现了一个快速信号鉴别器，以提供具有亚纳秒抖动的触发器。该芯片是专门为满足CALICE合作开发的模拟强子量热计（AHCAL）的限制而设计的，用于下一个线性对撞机实验。低功耗和使用功率门控的可能性已经集成在芯片中，以解决这种高粒度检测器系统的严重功率限制。在占空比为1%的情况下，每个通道的平均功耗为25 μ W，而不会影响芯片的读出能力。混合信号版本与数字读出计划为未来版本的ASIC。
KLauS is an application specific integrated circuit (ASIC) for the readout of silicon photomultipliers (SiPM) developed in the 0.35 µm SiGe technology. It has been designed to provide a high precision charge measurement of the SiPM signal with a high dynamic range. In addition a fast signal discriminator has been implemented to provide trigger with a sub nanosecond jitter. The chip was specifically designed to satisfy the constraints of the analog hadronic calorimeter (AHCAL) developed by the CALICE collaboration for the next linear collider experiment. A low power consumption and the possibility to use power gating have been integrated in the chip in order to address the severe power constraints of this highly granular detector system. For a duty cycle of 1% an average power consumption of 25 µW per channel is achieved without affecting the readout capabilities of the chip. A mixed signal version with digital readout is planned for future versions of the ASIC.
