By defining a pattern of one bit set to “1” and remaining bits set to “0” we generate a monopulse. By defining multiple patterns accordingly we generate time-hopping waveforms for multi-users. In order to shape the generated monopulses, either we apply them directly to the transmit antenna or we combine the complementary outputs after shifting one of them. Some experimental results are shown.","PeriodicalId":251525,"journal":{"name":"2011 18th IEEE International Conference on Electronics, Circuits, and Systems","volume":"396 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114918275","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}

Research in the field consists of new reconfig-urable architectures, either coarse-grain or fine-grain, and new methodologies to map applications onto them. A special case of coarse-grain reconfigurable components are morphable multipliers, which use multiplexers to feed different inputs and form different connection schemes within the datapath of conventional multipliers. These connection schemes form different components that can be utilized when the initial multiplier is idle. Morphable components offer performance improvements but the use of extra multiplexers impose power overheads. This paper applies two low-power design techniques, power gating and multi Vth components, for the design of low-power morphable multipliers. Experimentation with these multipliers show that they can offer performance, area and power improvements compared to other alternative architectures, making them valuable building blocks for hardware synthesis.","PeriodicalId":251525,"journal":{"name":"2011 18th IEEE International Conference on Electronics, Circuits, and Systems","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126563871","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}

The synchronizer has two variants one operating by both transitions at bit rate and other operating by positive transitions at quarter rate. Each variant has two versions namely the manual and the automatic.

Typically multiple RAT devices will be comprised of multiple RF power amplifiers, low noise amplifiers (LNA), RF band pass filters, modulators and demodulators; one for each wireless technology. Obviously, this will increase the complexity of the circuit design and will cover a large part of the circuit space leading to power hungry devices. Radio frequency microelectromechanical systems (RF-MEMS) can be good candidate for innovative RF front end devices since it is reconfigurable features in nature therefore allowing a reduction in the number of external components in a single device for the use of multiple RATs.
