本文采用对核辐射脉冲信号先积分再微分的方法把脉冲信号检测分离出来,然后经主放大电路放大。设计的电路具有较高的灵敏度、很好的线性度和强抗干扰能力。
In this paper, the method of integrating and differentiating the nuclear radiation pulse signal is used to separate the pulse signal detection and then amplified by the main amplification circuit. The circuit design has high sensitivity, good linearity and strong anti-interference ability.
