In designing of a high gain Op-Amp, for large values of coupling capacitor, gain will decrease. Since our requirement was to increase the gain, so we have designed a three stage Op-Amp. Our designed circuit provides gain of 78.4 dB, which is very much larger than two stage Op-Amp. There is a trade-off between various parameters like Phase margin, gain, slew rate etc. For example, to achieve larger values of GBW, PM will decrease. We have compared the results for two values of input common mode range. Improvement in the designed circuit is done to achieve the desired GBW by recalculating the transistor's W/L ratios and then simulating the results. Gain Bandwidth product of 176.9 MHz and Phase Margin greater than 60 degrees is achieved but at the cost of power dissipation and area. The Op-Amp is designed in gpdk 180 nm CMOS technology.","PeriodicalId":131816,"journal":{"name":"2015 Communication, Control and Intelligent Systems (CCIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130878920","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}

A sensor network is composed of a large number of sensor nodes, which are densely deployed and relay on limited battery power. In an Ad-Hoc network better Quality of Services can be achieved either by using high transmit power or by reducing number of hops. Transmitting at unnecessarily high power reduces the life time of sensor node as well as network. One of the goals of forming a network is to have power optimization-that is, each sensor node should be able to communicate with any other sensor node via less number of hops. Involving less number of intermediate sensor nodes in a route provides better QoS as well as rest sensor nodes can be involved in other transmission. The strategy of using optimum number of hop in multi hop communication is to provide less number of transmission in a route, which provides less involvement of semiconductor noise, signal interference, fading, scattering and shadowing, which ultimately improves QoS and also preserve the power of other sensor nodes.","PeriodicalId":131816,"journal":{"name":"2015 Communication, Control and Intelligent Systems (CCIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131179178","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}

Using the DGS technique a cross slot and circle are cut away at the centre of the ground plane to enhance the single band to multi band. The structure is asymmetrical along to the principal axes (x, y) because the radius of fractals are different and probe feed is applied at the diagonal of square patch then the excellent CP(circular polarization) is achieved. In the both techniques the proposed antenna sizes also reduce, besides the gain and directivity increase. Experimental results show as 10 dB return loss, gain and circular polarization at the frequencies 2.58, 3.02, 5.58, and 6.44 GHz. More over the 50 ohms feed position is optimized by moving the feed point along the diagonal of the square patch and get the effective gain and directivity grater then 6 dB at each frequency.

This new technique uses a method based upon angular fuzzy sets and a variation factor for calculating risk associated with variations or uncertainties involved in the solution of economic dispatch problem. Since the cost curve for each generator has inaccuracies and uncertainties, there is a need for including risk management in the solution of economic dispatch problem. This is to be noticed that inclusion of risk management in the solution does not reduce uncertainties, but it is providing a more accurate and precise solution considering uncertainty. Thus, this paper presents a method based on angular fuzzy sets and a variation factor that is capable of modeling economic dispatch problem including risk management.","PeriodicalId":131816,"journal":{"name":"2015 Communication, Control and Intelligent Systems (CCIS)","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133575924","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}
