5mm × 5mm sized slug on high power LED stress and junction temperature analysis
(Trans Tech Publications (TTP), 2013)
Conventional incandescent lamps are being replaced by high power light emitting diode as a lighting source due to it ascendancy in terms of physical size, performance, output and lifetime. Nevertheless, the reliability and ...
5-11 GHz CMOS PA with 158.9 ± 41 ps group delay and low power using current-reused technique
(Elsevier GmbH, 2012-11)
This paper proposes the design of a low group delay and low power ultra-wideband (UWB) power amplifier (PA) in 0.18 μm CMOS technology. The PA design employs two stages cascade with inductive peaking technique to provide ...
Objective evaluation of speech dysfluencies using wavelet packet transform with sample entropy
(Elsevier Inc, 2013-05)
Dysfluency and stuttering are a break or interruption of normal speech such as repetition, prolongation, interjection of syllables, sounds, words or phrases and involuntary silent pauses or blocks in communication. Stuttering ...
Shear speed analysis on Sn-3.9Ag-0.6Cu Solder
(Trans Tech Publications (TTP), 2013)
Ball Grid Array (BGA) is a type of semiconductor interconnection used in Integrated Circuit (IC) which is being scaled down to micro and nano size. The reliability of BGA in IC becomes a concern as the size of IC reduces. ...

(AENSI Publisher All rights reserved, 2013-10)
The light based surface finishing of most product measurement is an important feature in the industries. In this paper, a lab fabricated tester for investigation on the quality of low density paper which was represent by ...
Improved subtraction function for logarithmic number system
(Elsevier Ltd., 2013)
Logarithmic number system can be highly considered as an alternative to floating-point, specifically for applications that require a wide dynamic range of numbers for their arithmetic operations. To date, its implementation ...
Extended MASTAR modeling of DIBL in UTB and UTBB SOI MOSFETs
(Institute of Electrical and Electronics Engineers (IEEE), 2012-01)
This paper analyzes and models the drain-induced barrier lowering (DIBL) for ultrathin silicon body and ultrathin silicon body and thin buried oxide (UTBB) SOI MOSFETs. The channel depth appears as the primary factor in ...
FSS microchannel fluid flow profile investigation at high and low Re number
(AENSI Publisher All rights reserved, 2013-10)
The fundamental understanding of dynamic fluid flow behavior in different geometry channel is crucial due to transport phenomena influence on the key design and process control of the microfluidic systems. Recently, the ...
