中文摘要：

多阳极光电倍增管目前应用广泛，其后续的常规PCB放大电路显示出体积大、功耗大、噪声高等缺点，制作专用集成电路ASIC可以解决这些问题。基于此类光电倍增管特性，在0．35μmCMOS工艺上，研制了4通道集成放大成形读出电路，包含前放、增益调整、滤波成形等模块。经过测试，功耗为66roW；增益为62．2mV／pC，输入动态范围13pC，线性度1．5％，信噪比9，指标达到设计要求。

英文摘要：

MaPMTs is widely used , but conventional PCB circuits can not satisfy their demands because of the defects of large volume, high power dissipation and noise. The 4-channel readout ASIC for MaPMT is designed for solving these problems with 0. 35 μm CMOS technology. The circuit is composed of Pre- Amp, gain adjusting, and CR-RC shaper with Pole-zero cancling. The test results show power dissipation is 66 mW;gain 62.2 mV/pC;dynamic range 13 pC, INL=1. 5% ;SNR=9. 1. The performances meet design requires.
