From the principle of threshold value regulation of the Smitt circuit in the operational amplifier, the theoretical basis of compensating method and clamping method, has been found out, with results from experimental verification being attached. By analysing the interrelation among some basic curves, the key to the further improvement of the performance has been brought into view, thus making it possible to vary only one trigger value with the other trigger value remaining constant when regulating the hysteresis of the Smitt circuit. This novel type circuit is capable of directly transferring (shifting) photoelectric signals of a single fiber into counting pulses, sensibility being less than 5 mV and input impedance greater than 10~6Ω. When hysteresis range value increases by 390 times greater, the variation of one of the trigger values is only move 2.1 mV, being of high stability. These methods can also be used to identify and test other weak signals, which is helpful to flexibly and adaptably designing and applying operational amplifier Smitt circuit and to accurately setting up trigger values and hysteresis of Smitt circuit.

对于解决调节回差同时牵制两个触发阈的问题,本文从运算放大器施密特电路阈值调节的原理出发,提出了两种方法——补偿法和钳位法,并提供了实验验证的结果。又从几种基本曲线的相互关系的分析中阐明了进一步提高性能的关键,从而获得了调节回差时仅仅变动一个阈值,另一个阈值不变化的特有性能。这种改进的电路能将单纤维光电讯号直接转换成计数脉冲,灵敏度可达5毫伏以下。输入阻抗大于10~6欧姆。当回差值增加390倍时,其中一个阈仅变化2.1毫伏,可认为是相当稳定的。这种方法可以推广到其它微弱讯号的检测中,有助于灵活地设计和应用运算放大器施密特电路,精确地设置阈值和回差。
