CMOS集成计数器作率表式辐射仪的整形器,既可提高仪器的性能,又能简化仪器电路结构。本文简介其基本原理和电路。 一、原理 在率计式仪器中,一般用单一的双稳态触发器作整形器。这种整形器虽有对称射极跟随器隔离,但分辨时间仍嫌不够。其次,要通过改变定量电容来变换量程,转换切点 CMOS integrated counter as a form of radiation meter shaper, both to improve the performance of the instrument, but also simplify the instrument circuit structure. This article describes its basic principles and circuits. First, the principle In the rate meter, the general use of a single bistable trigger shaper. Although this shaper is symmetrical emitter follower isolation, but still not enough time to distinguish. Second, to change the quantitative capacitance by changing the range, switching point tangent
