摘　　要：　电荷放大器是粒子描迹仪系统中一个重要组成部分,它的目的是把多丝正比室输出的弱电信号进行放大并处理为准高斯信号以供CIA(电流积分型ADC)电路进行数字化。整个电路主要包括放大、成型两个部分。可把不同幅度的输入脉冲放大成型为宽度600ns的准高斯波形。In particle track system in Beijing, the signal from Multi-Wire Proportional Chamber(MWPC) is measured for obtaining the track of particle. Charge amplifier is an important component of this system. It can amplify and shape the small signal from MWPC before CIA(Charge Integrating ADC) converts it. The amplifier contains amplifying stage and shaping stage, and can convert the small signal from MWPC to large one whose width is 600ns.
