我们介绍了一种用于未来直线对撞机成像量热计的低功耗硅光电倍增管电荷读出ASIC的研制。模拟前端旨在使用低增益SiPM为单像素信号实现足够的信噪比，同时允许在传感器的整个动态范围内进行电荷测量。前端由一个输入级、两个电荷测量支路和一个快速比较器组成。分辨率为10位的合成孔径雷达模数转换器将脉冲高度信息数字化。附加的流水线合成孔径雷达级允许将量化分辨率提高到12位以进行校准测量。
We present the development of a low power Silicon Photomultiplier charge readout ASIC for an imaging calorimeter at a future linear collider. The analog front-end is designed to achieve sufficient signal-to-noise ratio for single pixel signals using low gain SiPMs, while allowing charge measurements over the full dynamic range of the sensors. The front-end consists of an input stage, two charge measurement branches and a fast comparator. A SAR ADC with a resolution of 10 bit digitizes the pulse height information. An additional pipelined SAR stage allows to increase the quantization resolution to 12 bit for calibration measurements.
