The contents are: Instructor Notes.doc – this document. labviewIntroduction-SixHour.ppt – a PowerPoint presentation containing screenshots and notes on the topics covered by the course. Convert C to F (Ex1).vi – Exercise 1 solution VI. Convert C to F (Ex2).vi – Exercise 2 solution subVI. Thermometer-DAQ (Ex2).vi – Exercise 2 solution VI. Temperature Monitor (Ex3).vi – Exercise 3 solution VI. Thermometer (Ex4).vi – Exercise 4 solution subVI. Convert C to F (Ex4).vi – Exercise 4 solution subVI. Temperature Logger (Ex4).vi – Exercise 4 solution VI. Multiplot Graph (Ex5).vi – Exercise 5 solution VI. Square Root (Ex6).vi – Exercise 6 solution VI. State Machine 1 (Ex7).vi – Exercise 7 solution VI. The slides can be presented in two three hour labs, or six one hour lectures. Depending on the time and resources available in class, you can choose whether to assign the exercises as homework or to be done in class. If you decide to assign the exercises in class, it is best to assign them in order with the presentation. This way the students can create VI’s while the relevant information is still fresh. The notes associated with the exercise slide should be sufficient to guide the students to a solution. The solution files included are one possible solution, but by no means the only solution.

用MDK 生成bin 文件1用MDK 生成bin 文件Embest 徐良平在RV MDK 中，默认情况下生成*.hex 的可执行文件，但是当我们要生成*.bin 的可执行文件时怎么办呢？答案是可以使用RVCT 的fromelf.exe 工具进行转换。也就是说首先将源文件编译链接成*.axf 的文件，然后使用fromelf.exe 工具将*.axf 格式的文件转换成*.bin格式的文件。下面将具体说明这个操作步骤：1. 打开Axf_To_Bin 文件中的Axf_To_Bin.uv2 工程文件；2. 打开Options for Target ‘Axf_To_Bin’对话框，选择User 标签页；3. 构选Run User Programs After Build/Rebuild 框中的Run #1 多选框，在后边的文本框中输入C:\Keil\ARM\BIN31\fromelf.exe --bin -o ./output/Axf_To_Bin.bin ./output/Axf_To_Bin.axf 命令行；4. 重新编译文件，在./output/文件夹下生成了Axf_To_Bin.bin 文件。在上面的步骤中，有几点值得注意的是：1. C:\Keil\ARM\BIN31\表示RV MDK 的安装目录；2. fromelf.exe 命令的具体语法格式如下：命令的格式为：fromelf [options] input_file命令选项如下：--help 显示帮助信息--vsn 显示版本信息--output file 输出文件(默认的输出为文本格式)--nodebug 在生成的映象中不包含调试信息--nolinkview 在生成的映象中不包含段的信息二进制输出格式：--bin 生成Plain Binary 格式的文件--m32 生成Motorola 32 位十六进制格式的文件--i32 生成Intel 32 位十六进制格式的文件--vhx 面向字节的位十六进制格式的文件t--base addr 设置m32，i32 格式文件的基地址--text 显示文本信息文本信息的标志-v 打印详细信息-a 打印数据地址(针对带调试信息的映象)-d 打印数据段的内容-e 打印表达式表print exception tables-f 打印消除虚函数的信息-g 打印调试表print debug tables-r 打印重定位信息-s 打印字符表-t 打印字符串表-y 打印动态段的内容-z 打印代码和数据大小的信息

Agilent AN 154 S-Parameter Design Application Note S参数的设计与应用 The need for new high-frequency, solid-state circuitdesign techniques has been recognized both by microwaveengineers and circuit designers. These engineersare being asked to design solid state circuitsthat will operate at higher and higher frequencies.The development of microwave transistors andAgilent Technologies’ network analysis instrumentationsystems that permit complete network characterizationin the microwave frequency rangehave greatly assisted these engineers in their work.The Agilent Microwave Division’s lab staff hasdeveloped a high frequency circuit design seminarto assist their counterparts in R&D labs throughoutthe world. This seminar has been presentedin a number of locations in the United States andEurope.From the experience gained in presenting this originalseminar, we have developed a four-part videotape, S-Parameter Design Seminar. While the technologyof high frequency circuit design is everchanging, the concepts upon which this technologyhas been built are relatively invariant.The content of the S-Parameter Design Seminar isas follows:

本软件是关于MAX338, MAX339的英文数据手册：MAX338, MAX339 8通道/双4通道、低泄漏、CMOS模拟多路复用器 The MAX338/MAX339 are monolithic, CMOS analog multiplexers (muxes). The 8-channel MAX338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ω max, and the devices conduct current equally well in both directions. These muxes feature extremely low off leakages (less than 20pA at +25°C), and extremely low on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resistance, see the MAX328 and MAX329.

Integrated EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and State Universityin partial fulfillment of the requirements for the degree of Integrated EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed at an early stage without prototype implementation.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andradiation. Thermal models are built for the components. Thermal performance of thecircuit and the temperature profile of components are predicted. Improved thermalmanagement and winding arrangement are investigated to reduce temperature.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful information is obtained.
