Hence, the engineer must approximate as well as possible the prescribed network function by another function which is realizable. This paper describes a new approximation method for solving the problem of realizing passive network transfer functions, where the realization is carried out through the use of passive, reciprocal, lumped, linear, and time-invariant elements.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129108903","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}

In this case, the occupied area of the monopole slot chip antenna on the system circuit board can be further reduced. Antenna has a compact size of 20×20×0.8mm3. It size is minimized so that it can be easily installed to mobile handset. The simulated and measured results show that the impedance bandwidth covers the DVT (470∼860 MHz) band with return loss |S11| than 5.

However, existing techniques in sensor network design generally optimize only one objective while treating the others as constraints or convert the multi-objective optimization problem into a single objective optimization problem using weights associated with different objectives. The weighted sum approach is subjective and is incapable of obtaining multiple tradeoff solutions for non-convex optimization problems. A multi-objective optimization approach optimizes all objectives simultaneously and obtains multiple tradeoff solutions for non-convex problems without the need for a weight vector. This paper illustrates this approach by formulating and solving the sensor placement problem for energy efficient target detection as a multi-objective optimization problem.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130893610","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}

Compare to conventional STI diode, the lateral diode demonstrated superior Q-factor and TLP IT2 due to the reduced transport distance and RC constant. Aided by BSIM4 MOS transistor model, a physically based scalable lateral diode model was developed and presented here for the first time. The accuracy of the diode model was validated with RF characterization data over a broad device geometrical range. The model was successfully used in LNA and ESD CDM protection co-design. A good match of LNA RF performance between Si-data and model prediction was achieved for N+/PW and P+/NW lateral diodes. Experimental results showed that LNA with lateral diode protection passed +/−500V ESD CDM zap voltage, while LNA with STI diode started to fail at only−250V.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124748882","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}
