  • S参数的设计与应用

    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:

  • 基于Virtex5的PCI接口电路

    PCI Express是由Intel,Dell,Compaq,IBM,Microsoft等PCI SIG联合成立的Arapahoe WORK Group共同草拟并推举成取代PCI总线标准的下一代标准。PCI Express利用串行的连接特点能轻松将数据传输速度提到一个很高的频率,达到远远超出PCI总线的传输速率。一个PCI Express连接可以被配置成x1,x2,x4,x8,x12,x16和x32的数据带宽。x1的通道能实现单向312.5 MB/s(2.5 Gb/s)的传输速率。Xilinx公司的Virtex5系列FPGA芯片内嵌PCI-ExpressEndpoint Block硬核,为实现单片可配置PCI-Express总线解决方案提供了可能。  本文在研究PCI-Express接口协议和PCI-Express Endpoint Block硬核的基础上,使用Virtex5LXT50 FPGA芯片设计PCI Express接口硬件电路,实现PCI-Express数据传输

  • 开关电源EMI设计(英文版)

    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.

    This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to WORK with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051.
