| | This article attempts to propose theoretical computing formulas for input offset voltage and common mode rejection ratio of common emitter differential amplifier, common emitter-common base differential cascode amplifier and common emitter-common grid differential cascode amplifier. It proves that Early effect plays an important role so far as input offset and common mode rejection characteristics are concerned.In the past analysis on differential amplifiers offset characteristic and common mode rejection c... | | 本文以Early效应为主导线索,分析推导了共射(CE)差分级及共射-共基(CE-CB)、共射-共栅(CE-CG)串接差分级的输入失调电压Vos与共模抑制比(CMRR)的理论计算公式。证明Early效应对输入失调特性与共模抑制特性起着重要作用。文中还分析了后随级的非理想特性对输入失调电压温漂的影响,指出了实现低漂移功能块的匹配方法。据此分析而制作的低漂移运算功能块,其开环增益与共模抑制比均不低于120dB,失调电压温漂不大于±0.5μV/℃。 这种可用分立元件组装或可与单片集成前置级混合组装的功能块,可以作为自动控制与自动检测系统的高性能通用运算元件。 | | 文摘来源 | | The application of the photoelectric sorting method to mineral processing has made some progress at some tungsten mines in our country.In recent years,the method has been tested for quartz veined tungsten ore in leuco granite rock body and proved successful. Different kinds of minerals have different optical properties.The photoelectric sorting way is a separating process which changes the difference of certain optical property of minerals into the difference of electronic information.This diffuse refection... | | 我国的一些钨矿采用光电分选法选矿取得了一定的成效,近年来,对产于浅色花岗岩体内的石英脉型钨矿采用光电分选法进行了尝试,获得了成功。矿石的光学性质因物料不同而异。光电分选法是将物料的某种光学性质差异转变成为电子信息差异来进行拣选的一种选别方法。选矿中,最广泛采用的是漫反射分选法。漫反射分选法又分为单色分选法、双色分选法和复色分选法三种。通常是根据物料的漫反射差异的程度,选择其中的一种。采用光电分选法的关键在于能否将物料的光学性质的差异转变成足够的电子信息差异。由光源、背景、透镜装置、光敏元件等组成的检测系统,则是完成这一功能的,它被称为光电分选设备的“眼睛”。因此,对检测系统的设计考虑,是视拣选对象而定并且是十分讲究的。背景的选择是很重要的,它的光电信号是作为选别的基准,特别是对颜色相近的物料分选,精确选定背景光电信号的强弱尤为重要。围岩属花岗岩的石英脉型钨矿,因原矿是由花岗岩、石英、块钨等组成,花岗岩(废石)的漫反射光电信号的大小,介于石英与块钨之间。选择与花岗岩漫反射率相近的颜色作背景,运用漫反射分选法,是能够将花岗岩与石英、块钨分开的。本文介绍了运用漫反射分选法选弃花岗岩的意义、基本原理及方法,并提供了一... | | 文摘来源 | | In this paper, the resolution requirements of the image-detecting devices attached to a telescope, especially those of the electrographic cameras, and their developments in some countries as well as the question on the preferred types of devices to be developed, are discussed.For image-detecting devices designed to achieve limiting resolution in ground-based astronomical observations the seeing disk is the fundamental limiting factor, and for electro-graphic cameras using superconducting magnet ... | | 本文着重分析了光学天文观测对于望远镜终端图象接收器件,特别是电子照相器件的分辨率要求,讨论了合理选择器件研制课题的问题和国外的研制情况。 | | 文摘来源 | |   | | << 更多相关文摘 |
