Agilent AN 154 S-Parameter Design Application Note S參數的設計與應用 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:

PCI Express是由Intel，Dell，Compaq，IBM，Microsoft等PCI SIG聯合成立的Arapahoe Work Group共同草擬并推舉成取代PCI總線標準的下一代標準。PCI Express利用串行的連接特點能輕松將數據傳輸速度提到一個很高的頻率，達到遠遠超出PCI總線的傳輸速率。一個PCI Express連接可以被配置成x1，x2，x4，x8，x12，x16和x32的數據帶寬。x1的通道能實現單向312.5 MB／s（2.5 Gb／s）的傳輸速率。Xilinx公司的Virtex5系列FPGA芯片內嵌PCI-ExpressEndpoint Block硬核，為實現單片可配置PCI-Express總線解決方案提供了可能。 本文在研究PCI-Express接口協議和PCI-Express Endpoint Block硬核的基礎上，使用Virtex5LXT50 FPGA芯片設計PCI Express接口硬件電路，實現PCI-Express數據傳輸

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.

They have been developed using the AZTEC C86 compiler, and are portable to any other standard C environment. I have tested this code with AZTEC CII for the 8080, and with the C compiler on XENIX 286, and they Work fine.

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.
