摘 要: | 介绍了峰值保持电路的工作原理,并针对脉冲宽度为500 ns左右的高速高斯输入脉冲,设计了几种实用的峰值保持电路。先后采用LF398与OPA615采样保持芯片,实现了2种峰值保持电路,并测试了相关电路的性能。电路结构简单,且能在一定程度上达到峰值保持的目的。 |
关 键 词: | 原子核物理学;峰值保持;LF398;OPA615;高速脉冲 |

Abstract: | We introduced operational principal of peak-holding circuit and designed several useful peak-holing circuits for high-speed Gauss pulse with 500 ns pulse width. We use LF398 and OPA615 to sample and hold IC to get two kinds of peak-holding circuits and test their features. With simple structures, these circuits, to some extent, can reach the target of peak-holding. |
