By incorporating the dynamic multiple path convergence scheme, the survivor path can be determined at earlier stage such that the overall survivor memory access can be reduced. The experimental results show that the average memory reference can be reduced up to more than 30% for digital video broadcasting (DVB) application at high signal-to-noise ratio. The bit-error-rate (BER) performance of the proposed approach can be even better in some cases. This approach can lead to the reduction of power since memory operation is considered as the major power consumption of the entire decoders. An efficient VLSI architecture of Viterbi decoder for DVB standard is also presented based on the proposed design methodology. One salient feature of this architecture is that the survivor memory can be implemented by using only three single-port memory banks","PeriodicalId":356198,"journal":{"name":"2006 International Symposium on VLSI Design, Automation and Test","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130379580","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 Power Efficient and Fast Transient Response Low Drop-Out Regulator in Standard CMOS Process 标准CMOS工艺中一种高效、快速的瞬态响应低差稳压器

As we know, LDO circuits have to provide a regulated output voltage regardless of input voltage variation, load current variation, and process variation. A load transient test will test the transient behavior of changing output loading. In order to get a good performance in a load transient testing, a buffer with current driving capability is usually added in front of PMOS gate to make the transient response faster. This buffer needs to drive the PMOS gate, and it will consume a few quiescent current in LDO circuits. This static quiescent current will occupy a few percentage of power consumption of LDO circuits at a light load condition, and the efficiency of the LDO at a light load condition will be very poor. In this paper, we proposed a new architecture of LDO, which can adaptively change the driving current of the buffer to the PMOS gate. Then we can improve the efficiency of the LDO up to 10% at light load condition. Meanwhile, we can have a fast transient response time. The load transient response time from 1mA to 138mA is about 2mus, which is faster than other reference designs. This chip is manufactured in 0.35mum standard CMOS process, and it consumes 24muA in a light load condition","PeriodicalId":356198,"journal":{"name":"2006 International Symposium on VLSI Design, Automation and Test","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125911164","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 old good days, when the process and the design engineers were in each technology silo and didn't need to interact frequently, have gone. As the device size shrinks to nanometer scale and the integration level exceeds well over giga scale, the landscape of technology developments has become very different from the past. The variability, for example, becomes a critical issue not only for performance, but also for production yield. The problems, which have been seen as secondary for long time, suddenly come into play and will grow according to the device size reduction. The solution is DFM, design for manufacturing. The DFM will not be done without collaborations between various technology parties, such as process, design, mask, EDA, and so on. The DFM will give us a big challenge and opportunity in nanometer era. In this talk, the perspective of the DFM was presented and how the work-flow for making chips should be changed was discussed.
