The performance of two oscillators topologies, LC VCO and distributed oscillator, is compared. Simulation results show that the 30 GHz distributed oscillator has better phase noise compared to that of 60 GHz LC oscillator. The phase noise of DO is −101.85 dBc/Hz at 1 MHz offset from 30 GHz carrier while that of LC oscillator, it is −88.88 dBc/Hz at 1 MHz offset from 60 GHz carrier. A doubler is then used to double the DO frequency to 60 GHz but phase noise remains the same. Thus the 30 GHz distributed oscillator or even an LC VCO at 30 GHz, with a doubler can be used to achieve better phase noise performance at a higher frequency of 60 GHz. The 30 GHz LC VCO of phase noise −99.85 dBc/Hz at the same time has lesser DC power consumption than 60 GHz LC VCO. The 30 GHz DO and LC VCO has better FoM due to better phase noise performance, as compared to 60 GHz LC VCO. A 60 GHz LC QVCO has also been implemented having better phase noise than 60 GHz LC VCO. The QVCO provides 90° quadrature phase signals at its output. This work compares for the first time the performance of a distributed oscillator with that of an LC VCO and QVCO.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116208285","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}

OPEN UPQC models with and without storage units are devised. An OPEN UPQC consists of two voltage source inverters, i.e., series and shunt inverters. Without storage units, the series inverter is used to protect all the downstream loads of a network from voltage sag and the shunt inverter is used to provide harmonics and reactive power compensations. In addition, both the inverters with storage units are used to provide active power compensation. The impact of the OPEN UPQC placement on distribution networks is studied by placing one of its inverters in each bus, one at a time and by fixing the location of the other inverter at a particular bus. The OPEN UPQC model is suitably incorporated to the forward-backward sweep load flow algorithm. The simulation results show that significant amount of power loss reduction can be obtained if the shunt inverter is placed at some specific locations. The series inverter can be used to protect higher amount of loads if it is placed near to the substation.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121112968","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}

One such issue is voltage variation arising due to intermittent nature of wind energy sources. Thus, it is necessary to maintain the power quality in the grid. In this context, FACTS devices may play a significant role in improvement of voltage profile resulting in system stability. This paper presents the voltage regulation improvement of a grid integrated wind farm using static synchronous compensator (STATCOM). The wind farm consists of turbines coupled with induction generators. The entire system is simulated using MATLAB/Simulink for different loads (i.e. resistive, inductive and capacitive) under variable wind speeds experienced by the turbines. Results show that the STATCOM can effectively stabilize the bus voltage and improve the stability of the system by controlling the reactive power.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116466763","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 proposed device exhibits better performance in comparison with homojunction of the same device for different temperature. The effect of temperature is studied in terms of DC analysis as well as on AC analysis such as input characteristics, output characteristics, drain current, subthreshold swing (SS), threshold voltage, ION/IOFF ratio, transconductance, transconductance-to-drain-current-ratio, gate capacitance. This study reveals that OFF current of the device is independent of drain voltage variation irrespective of temperature variation. A small change in SS with temperature variation shows the weaker dependence of SS on temperature. A small variation in analog parameters with temperature variation shows that the device could be used for the high-temperature applications. A broad range of temperature from 200 K to 400 K has been used to analyze the performance of the device using Synopsys Technology Computer Aided Design (TCAD) simulation tool.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126877761","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}

PS technique has been used to demodulate the phase information from multiple phase shifted interferograms; whereas FT is used to extract phase information from a single interferogram. In this paper, we perform a comparative analysis of PS and FTM technique using simulation analysis. The techniques are assessed based on two common problems, i.e. noise and non-sinusoidal waveforms (harmonics) that arise in the measurement system and reduce the accuracy. A new multi-step imaging technique is proposed by combining the advantages of PS and FTM and is also compared based on the same parameters. Advantages and drawbacks of each technique are also discussed.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131221953","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}
