In this paper, the authors systematically investigate the fluctuations of threshold voltages at varied gate length, considering the effects of channel doping, gate dielectric thickness, and new transistor structures such as thin-buried-oxide SOI and FinFETs. Quantitative analysis is undertaken in terms of three major variation sources: random doping distribution, gate length deviation, and line edge roughness. The analysis also features a low Vt-fluctuation transistor for 16nm node achieved with undoped body, mid-gap metal gate, and nanowire channel","PeriodicalId":269854,"journal":{"name":"IEEE Custom Integrated Circuits Conference 2006","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129379517","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}

While those challenges carry across the spectrum of the manufacturing, the EDA, and the design communities, we believe it is the responsibility and the goal of the EDA industry to deal with those issues as thoroughly and as seamlessly as possible to make those challenges transparent to the designer. In this paper we expose and analyze a plurality of those challenges and briefly go over the solutions EDA tools are offering for dealing with them.

However, the output power from an energy harvester is highly variable. We propose a domain-specific computational array which maximizes sensor performance by matching system power consumption to the available scavenged energy through power scalable approximate signal processing. The array consists of distributed arithmetic (DA) based functional units coupled with a reconfigurable interconnect structure. Each unit implements several core linear and nonlinear signal processing functions in an area efficient manner which also minimizes leakage power. Several sensor DSP applications (FIR, IIR, and FFT) have been mapped onto the array.
