Optical link employs laser, optical fiber and optical detector to transmit RF signal. RoF has an ability to carry signals for tens of kilometers, but this transmission is limited by optical impairments such as laser nonlinearity, fiber dispersion, and optical detector noises. In this paper, we study the effects of multimode fiber core refractive index profile, optical detector noises and atmospheric instability on the achievable performance of an OFDM based RoF link. The optical-signal-to-noise ratio (OSNR) and cumulative signal-to-noise ratio (SNRc) are used to evaluate the feasibility of the proposed scheme for a low-cost, reliable, robust, and high data rate fiber-wireless link. Thereafter, numerical results are generated for the downlink to illustrate the performance of the OFDM based RoF system.","PeriodicalId":137085,"journal":{"name":"2011 21st International Conference on Noise and Fluctuations","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126647295","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 these engines, there is no steam, gas or combustion and the only mechanically moving elements are the piston and resonator (flywheel). Resistors, capacitors and electronically controlled switches are the other building elements. For the best performance, a large number of parallel engines must be integrated to run in a synchronized fashion. At room temperature, in the idealistic case, a two-dimensional ensemble of engines of 25 nanometer size integrated on a 1 square-inch silicon chip with 20 °C temperature difference between the warm-source and the cold-sink would produce a power of about 1 Watt. Several standard and coherent (correlated-cylinder states) versions of these engines have been introduced and both of them can operate in either four-stroke or two-stroke modes. The correlated engines offer the same type of paradoxes as coherent quantum heat engines and they serve the solution of their paradox, too.","PeriodicalId":137085,"journal":{"name":"2011 21st International Conference on Noise and Fluctuations","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114493035","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}

Supercapacitors in bias systems for low frequency noise measurements 低频噪声测量偏置系统中的超级电容器

Ciofi","doi":"10.1109/ICNF.2011.5994351","DOIUrl":"https://doi.org/10.1109/ICNF.2011.5994351","url":null,"abstract":"We explore the possibility of employing supercapacitors in the design of very low noise programmable voltage and current sources to be used for biasing the device under test in low frequency noise measurements. This is accomplished by taking advantage of the large capacitance of supercapacitors for realizing a low pass filter with a very low frequency corner for filtering out the noise produced by a solid state high accuracy DA converter. In order to obtain the desired attenuation of the noise down to a few hundred mHz, a very low frequency corner must be employed, thus resulting in very long transients (in the order of a few hours) upon each voltage change. This problem is specifically addressed in this paper. Indeed, we have designed a programmable voltage reference capable of generating voltages in the range 0–2.5 V with a resolution of about 2.5 mV, an accuracy better than 2 mV and a settling time of about 200 s. The output noise is below 4×10−16, 5×10−18, and 1×10−18 V2/Hz at 100 mHz, 1 Hz, and 10 Hz, respectively. The application of such a low voltage reference for the realization of a very low noise programmable current source is also discussed and demonstrated.","PeriodicalId":137085,"journal":{"name":"2011 21st International Conference on Noise and Fluctuations","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129578091","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}
