模拟电子 为什么我的CMOS逻辑电路烧起来了
Abstract: What can be simpler than designing with CMOS and BiCMOS? These technologies are very easy to use butthey still require careful design. This tutorial discusses the odd case of circuits that seem to work but exhibit somepeculiar behaviors—including burning the designer's fingers! ...
模拟电子 ISM射频产品的晶体频率计算
Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) products use crystal oscillators to generate areference for the phase-locked loop (PLL)-based local oscillator (LO). This tutorial provides a basic description of theISM-RF Crystal Calculator, which can be used to calcula ...
模拟电子 校准触摸屏系统研究
Abstract: Mechanical misalignment and scaling factors lead to a mismatch between the values coming from a touchscreen panel (as translated by a touch screen controller) and the display (typically an LCD) on which the touch screenpanel is mounted. This tutorial discusses how to calibrate the touch ...
模拟电子 信号链和PLC是如何影响我们的生活
Abstract: It is incredible how many programmable logic controls (PLCs) around us make our modern life possible and pleasant.Machines in our homes heat and cool our air and water, as well as preserve and cook our food. This tutorial explains the importanceof PLCs, and describes how to choose compon ...
模拟电子 数控DCDC转换器在便携产品中的应用
Abstract: This tutorial discusses methods for digitally adjusting the output voltage of a DC-DC converter. The digital adjustmentmethods are with a digital-to-analog converter (DAC), a trim pot (digital potentiometer), and PWM output of a microprocessor.Each method is assessed and several DACs and ...
模拟电子 数据采集电路分析
 
This application note features 8-, 10-, and 12-bit dataacquisition components in various circuit configurations.The circuits include battery monitoring, temperature sensing,isolated serial interfaces, and microprocessor andmicrocontroller serial and parallel interfaces. Also includedare v ...
模拟电子 逐次逼近式AD转换器研究
A tutorial on SAR type A/D converters, this note contains detailed information on several 12-bit circuits. Comparator, clocking, and preamplifier designs are discussed. A final circuit gives a 12-bit conversion in 1.8µs. Appended sections explain the basic SAR technique and explore D/A consi ...
电源技术 电能计量和安全性的智能电网
Abstract: It may sound trite, but it is definitely true: the smart grid has the potential to completely transform the energyindustry. However, smart meters and grid management alone will not ensure the success of the smart grid. Unliketraditional IT networks, smart grids require consideration of e ...
电源技术 电源工程师-电路设计中的英雄
Abstract: We don't expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can't solve all issues—each application has different ESD requirements.Knowing that "one size fits all" cannot apply to power design, the power designer, ...
电源技术 智能电网安全保护
Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to learn something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. ...
