The compromise between complexity, technology and compatibility is central frequency 2-5 GHz, which corresponds to short (<500 ps) pulse having 2-4 half periods at pulse repetition rate 10-100 MHz. Time position control should be down to 10 ps. Peak power reaches tens and hundreds Wtts even at low average powers. Randomly hoping period requires low, \"previous periods memory\", a new, poor known, requirement. The inherent for usual power semiconductor devices output low impedance cannot be effectively matched with higher impedance of an UWB antenna. The best technology is power compression by use of new semiconductor drift step recovery devices, including two types: Drift Step Recovery Transistors (DSRT), Drift Step Recovery Diodes (DSRD). The best antennas for UWB are arrays of TEM horns, where the low cut off frequency is limited by E-plane span. The most critical part of array is a power splitter. The best solution is an active array, when separate pulser, synchronized with others, feeds a horn. It may be stated that discussed technologyes are able to solve practically all current problems in UWB communication, positioning and radars.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121365081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmission line properties of on-chip wiring need to be taken into account due to the great lengths and fast rise times encountered. Coupling noise between adjacent interconnects can also cause catastrophic effects on the logical functionality and long-term reliability of a VLSI circuit. With these trends, the electrical phenomena that have to be investigated are governed by the electromagnetic theory. However, it's impossible to proceed to a complete SOC - AMS analysis with a full wave electromagnetic numerical tool, due to the large scale integration. As interconnects are typically of very large size and high-order, model-order reduction becomes necessary for efficient SOC modeling, simulation, design and optimization. In this communication, a new method based on numerical inversion of Laplace transform and on a discrete model-reduction technique is presented for simulating peak crosstalk noise problems found in high speed digital circuits and SOC-AMS. The method, particularly efficient and easy to be implemented in a program, is useful for an electromagnetic simulation of a complete system.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125506667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These self-calibration procedures have the advantage that the calibration circuits are all of equal mechanical length in contrast to the well-known TRL method (Through, Reflect, Line). The TRL method needs a line-standard with a different length than the other calibration standards. For the LNN and LRR method it is thus not necessary to displace the connectors of the vector network analyzer during calibration in order to contact the calibration structures. The LNN and LRR calibration standards consist of objects which have to be placed at three consecutive positions. While the LNN obstacles have a transmission, the LRR obstacles are realized as reflective networks. In addition to the known LNN procedure an extended theory is presented here which accounts for different distances between the obstacles. The circuits are thus easy to realize. Measurement results are presented in order to verify the robust functionality of the methods.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121916093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
