摘要

本文介绍了用于快－快定时系统的微分恒比甄别器。它既有定时功能，又有能量选择功能。当输入信号的上升时间为1ns、幅度从-50mV到-5V时，其时间游动是120ps。文章给出了快－快定时系统在不同动态范围的时间分辨率。当动态范围为1.4:1时，其半宽度是201ps。

Abstract

A constant fraction differential discriminator used in a fast-fast timing system is described. The discriminator performs both timing and energy range selection functions. The time walk is 120ps for 1 ns risetime input signal from -50mV to -5V. The time resolution as a function of dynamic range in a fast-faft timing system is given. The FWHM is 201 ps when measured with 1.4:1 dynamic range.
