Scaled-up Nonequilibrium Air Plasmas
The volume scalability of nonequilibrium plasmas produced by electrical discharges in atmospheric pressure air has been investigated. A variety of direct current (DC) and pulsed glow discharges obtained in either slow flow of ambient or fast flow of preheated (~2000 K) air at atmospheric pressure is presented. Single DC and repetitively pulsed discharges represent the first approach. Stable dis...
متن کاملScaled-down nuclease P1 for scaled-up DNA digestion.
Motivated by an interest in detecting DNA adducts in their nucleotide form by mass spectrometry (1), we sought efficient, low-cost conditions for enzymatic digestion of a relatively large amount of DNA (≥ 1 mg). Of the enzymes available for such digestion, nuclease P1, which forms deoxynucleoside-5′-monophosphates, seemed to be a good initial choice because it is widely used for digesting DNA, ...
متن کاملLow Power Analog Design in Scaled Technologies
In this paper an overview on the main issues in analog IC design in scaled CMOS technology is presented. Decreasing the length of MOS channel and the gate oxide has led to undoubted advantages in terms of chip area, speed and power consumption (mainly exploited in the digital parts). Besides, some drawbacks are introduced in term of power leakage and reliability. Moreover, the scaled technology...
متن کاملDirect Sampling Methodology for Statistical Analysis of Scaled CMOS Technologies
The continued scaling of CMOS technologies introduces new difficulties to statistical circuit analysis and invalidates many of the methodologies developed earlier. The analysis of device parameter distributions reveals multiple sources of parameter correlations, some of which exhibit mutually opposing trends. We found that applying principal component analysis (PCA) to such heterogeneous statis...
متن کاملCircuits and algorithms for pipelined ADCs in scaled CMOS technologies
CMOS technology scaling is creating significant issues for analog circuit design. For example, reduced signal swing and device gain make it increasingly difficult to realize high-speed, high-gain feedback loops traditionally used in switched capacitor circuits. This research involves two complementary methods for addressing scaling issues. First is the development of two blind digital calibrati...
