摘要

由场效应管与晶体管构成的源-射耦合触发器

其触发电流远小于1μA。本文对该种触发器进行了分析

给出了求取触发电平的计算公式

指出了有可能获得零温度系数触发电平的触发器。当某种条件得到满足时

该触发器还具有记忆特性

从而可借以构成一种不可逆的触发电路。理论分析与实验结果基本相符。

Abstract

: The source-emitter coupled trigger

which consists of a FET and a bipolar transistor

possesses extremely small triggering current（《1μA）. In this paper

an analysis of the circuit was made

a theoretical formula was given to determine the triggering level

and the possibility of achieving triggering level with zero temperature coefficient was confirmed.It was found that the trigger would exhibit a memory property for Ipss >Us/Rs [1 - （Us/ |Ur| ）]Z. This feature makes it possible to design a non-reversible triggering circuit.The theoretical analysis agrees with experimental results.
