| 摘 要： | 正 一 当被测量的物理量正比于某一非周期三角形脉冲的峰值时,为了读取被测量值,通常采用二极管峰值保持电路。非周期的三角形电压脉冲,记为u1(t),如图1所示。Um是脉冲的幅值,t1和t2分别是脉冲的前沿和后沿宽度,1和2是脉冲前沿和后沿的斜率,那么 1=Um/t1,2=Um/t2。 常用的二极管峰值保持电路,如图2所示,图中BG1是射极跟随器,D是开关二极管,C是存储电容器,BG2是源极跟随器。为了便于分析,用R0表示前级的输出阻抗

| Abstract: | When an input signal is a non-periodic triangular pulse, an analysis is made of the relation between the input and the output signals. On the basis of the analysis, calculations are made of the trapping time, trapping error and attenuation of the output signal.The non-linear characteristic of the diode is considered according to two different conditions, in the case where the volt-ampere characteristic can be represented in exponential form. The author proposes an iteration form to solve the intermediate region of the two conditions. |
