Abstract: Transimpedance amplifiers (TIAs) are widely used to translate the current output of sensors like photodiode-to-voltagesignals, since several circuits and instruments can only accept voltage input. An operational amplifier with a feedback resistor fromoutput to the inverting input is the most straightforward implementation of such a TIA. However, even this simple TIA circuit requirescareful trade-offs among noise gain, offset voltage, bandwidth, and stability. Clearly stability in a TIA is essential for good, reliableperformance. This application note explains the empirical calculations for assessing stability and then shows how to fine-tune theselection of the feedback phase-compensation capacitor.

摘要 本研究計劃之目的,在整合應用以ARM為基礎的嵌入式多媒體實時操作系統于H.264/MPEG-4多媒體上。由于H.264是一種因應實時系統(RTOS)所設計的可擴展性串流傳輸(scalability stream media communication)的編碼技術。H.264主要架構于細細??蓴U展(Fine Granula Scalability,FGS)的壓縮編碼機制。細粒度可擴展壓縮編碼技術是最新MPEG-4串流式傳輸標準,能依頻寛的差異來調整傳輸的方式。細粒度擴展縮編碼技術以編入可選擇性的增強層(enhanced layers)于碼中,來提高影像傳輸的質量。本計劃主要在于設計一種簡單有效的實時階層可擴展的影像傳輸系統。在增強層編碼及H.264的基本層(base layer)編碼上使用漸進的細粒度可擴展編碼(Progressive Fine Granularity Scalable,PFGS)能直接使用H.264的格式特色來實現FGS。同時加入了LB-LLF(Layer-Based Least-Laxity-Fir stscheduling algorithm)的排程算法,來增 進網路傳輸影像的質量。由實驗結果顯示本系統在串流影像質量PSNR值上確有較佳的效能。

A Computer-On-Module, or COM, is a Module with all components necessary for a bootable host computer, packaged as a super component. A COM requires a Carrier Board to bring out I/O and to power up. COMs are used to build single board computer solutions and offer OEMs fast time-to-market with reduced development cost. Like integrated circuits, they provide OEMs with significant freedom in meeting form-fit-function requirements. For all these reasons the COM methodology has gained much popularity with OEMs in the embedded industry. COM Express® is an open industry standard for Computer-On-Modules. It is designed to be future proof and to provide a smooth transition path from legacy parallel interfaces to LVDS (Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA on the one hand and PCI Express and Serial ATA on the other hand.

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:

Logger iButton devices have gained a lot of popularity with researchers. Although free evaluation software is easy to use and welldocumented, the choices and inputs that need to be made can sometimes be challenging. This application note explains technicalterms that are common with temperature logger iButtons and how they relate to each other. Additionally, it presents an algorithm tohelp users choose the necessary input parameters, including the sample rate based on a user's needs and the available memory tostore the data.

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.

Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.
