The proposed boost converter utilizes a dynamic stored energy technique to reduce output voltage variation and raise power conversion efficiency. This result is realized using a dynamic stored energy controller and a load current detector that accurately generates different energy according to various load conditions. The output up-ripple voltage variation and steady-state accuracy was 2.6 mV (5.7 mV-8.3 mV) and 0.15% whereas its fixed energy counterpart was 11.1 mV (8.1 mV-19.2 mV) and 0.35%, respectively. The proposed circuit has 6.91% higher power-conversion efficiency than conventional fixed energy technique at a 1 mA current. The maximum power-conversion efficiency is 91.75% for 50 mA output current with a 1.5 V supply.","PeriodicalId":404629,"journal":{"name":"2008 15th IEEE International Conference on Electronics, Circuits and Systems","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134097386","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}

This is then integrated into the Simulink/Stateflow (SS) tool framework from MathWorks Inc., where the validation of the ACC is carried out using simulation on the differential equation based and analytical function based continuous time domain dynamic behavior.

The model also considers the design of the driver stages, calculates the switching power loss and adjusts the efficiency to obtain the effective value.

It makes use of two modulation signals per phase. The hybrid modulation is based on combining two modulation strategies; double-signal PWM and sinusoidal PWM. The main characteristic of the hybrid modulation is the capacity to reduce switching losses at the cost of having some low-frequency voltage oscillations on the neutral point. The amplitude of these oscillations can be controlled by varying the combination of the two strategies. The tracking method proposed in this paper defines the intervals in which sinusoidal PWM should be used to achieve the maximum reduction of the voltage oscillation amplitudes. Consequently, the low-frequency neutral-point voltage oscillation is further minimized. Some simulation results are presented to show good performance of the proposed strategy and are compared with the nontracking method.","PeriodicalId":404629,"journal":{"name":"2008 15th IEEE International Conference on Electronics, Circuits and Systems","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121719063","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}

Since choosing an optimum word-length is a tradeoff between design costs and accuracy, it is essential to have an accurate model of computational errors for each operation. Errors resulting from the output rounding or truncation of the functional units is generally considered as uniformly distributed over the error limits regardless to the functionality of the unit. This work presents an analysis of the probability distribution of a fixed-point multiplier and its output truncation error. Simulations show that the uniform distribution assumption is violated in the case of truncation of a multiplication result of less than 8 bits.","PeriodicalId":404629,"journal":{"name":"2008 15th IEEE International Conference on Electronics, Circuits and Systems","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126498058","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}

Based on an innovative architecture, this is the first implementation of fully parallel RS turbo decoder. A performance analysis is performed showing that RS block turbo codes (RS-BTC) have decoding performance equivalent to Bose Ray-Chaudhuri Hocquenghem-block turbo codes (BCH-BTC). A ratio between the decoder throughput and the decoder area is used to show the higher efficiency of the RS full parallel turbo decoder. Finally an implementation of a (31,29)2 RS block turbo decoder on a high performance board including 6 Xilinx Virtex5 FPGAs is detailed. The resulting turbo decoder has an information throughput above 6 Gb/s while the working frequency is only 45 MHz.
