本着自力更生的革命精神,我们根据国产P-MOS数字集成电路与线性集成电路的性能与特点,研制了色谱仪用数字积分仪,经试验证明性能可靠,现将电路设计介绍如下: 一、色谱峰检测电路色谱峰检测电路是确定色谱峰的始点、顶点和终点的电路。它由非线性放大器、微分器、比较器等部分组成,见图2。非线性放大器将输入的色谱信号放大,由于二极管D_1的非线性特点,对小信号的
In the revolutionary spirit of self-reliance, based on the performance and characteristics of domestic P-MOS digital integrated circuits and linear integrated circuits, we developed a digital integrator for chromatographs and proved to be reliable by experiments. The circuit design is described as follows: 1. Chromatography Peak Detection Circuit The peak detection circuit is the circuit that determines the start, top, and end of a chromatographic peak. It consists of non-linear amplifiers, differentiators, comparators and other components, shown in Figure 2. The nonlinear amplifier amplifies the input chromatographic signal. Due to the nonlinear characteristic of the diode D_1, the small signal
