摘　　要：提出了一种崭新的基于数值微分法的时域内核脉冲信号放大电路的分析方法,弥补了频域分析方法在脉冲信号的宽度、形状和幅度特性分析上的不足。从实际信号放大电路出发,运用基尔霍夫电流定律,建立输入信号和输出信号之间的一阶微分方程关系等式。方程解算过程中,利用数值微分算法求解,获得输入输出之间的数学关系模型。通过反相放大电路和同相放大电路等实际电路的测试结果,表明时域内运用数值微分算法研究核脉冲信号放大电路的方法是可行的。In the time-domain, a novel method of nuclear pulse signal amplifier circuit is presented based on numerical differential in this paper. The method can cover the many shortages of the analyzing methods in the frequency-domain, such as pulse width, shape and amplitude. According to the Kirchhoff＇s current law, an equation between input and output is established based on actual signal amplifier circuits. And after equation is solved, the mathematical model can also be acquired by using numerical differential. The simulating results of the inverting amplifying circuit and non- inverting amplifier circuit for nuclear pulse signal show that it is feasible for studying the amplifier circuits by using numerical differential method in the time-domain.
