L, C and X band integrated synthetic aperture radar (SAR) receiver
(Springer Science+Business Media New York, 2013-12)
An integrated receiver consisting of RF front ends, analog baseband (BB) chain with an analog to digital converter (ADC) for a synthetic aperture radar (SAR) implemented in 130 nm CMOS technology is presented in this paper. ...
Ionic contaminations level and cleaning flip chip BGA package via a new cleaning solvent technology
(Emerald Group Publishing Limited, 2013)
Purpose - This paper aims to discuss the effects of ionic contaminations on the die surface of high lead flip chip ball grid array (FCBGA) package. Ionic contaminations from the flux residue, formed during the die attachment ...
Low loss optimization of strip channel polysilicon waveguide fabrication
(American-Eurasian Network for Scientific Information, 2013)
Research on waveguide structures, its behaviour and material properties are very
extensive for a wide range of applications. Generally, waveguides are used for
optical devices such as biosensors. This paper investigates ...
UTBB SOI MOSFETs analog figures of merit: Effects of ground plane and asymmetric double-gate regime
(Elsevier Ltd., 2013)
In this work we investigate the effect of ground plane (GP) on analog figures of merit (FoM) of ultra-thin body and thin buried oxide (UTBB) SOI MOSFETs. Based on experimental devices, both n- and p-type GP configurations ...
Design and analysis of wideband ladder-type film bulk acoustic wave resonator filters in Ku-band
(Hindawi Publishing Corporation, 2013)
This paper presents the design of ladder-type filters based on film bulk acoustic wave resonator (FBAR) in Ku-band. The proposed FBAR filter has an insertion loss of -3 dB, out-of-band rejection of -12 dB and 3 dB bandwidth ...
Film bulk acoustic wave resonator filter for Ku-band applications
(Trans Tech Publications (TTP), 2013)
The design and analysis of Ku-band ladder-type filters based on film bulk acoustic wave resonator (FBAR) is presented. The proposed FBAR filter has an insertion loss of -3dB, out-of-band rejection of -12dB, centre frequency ...
Optimal selection of long time acoustic features using GA for the assessment of vocal fold disorders
(Trans Tech Publications, 2013)
In recent times, vocal fold problems have been increasing dramatically due to unhealthy social habits and voice abuse. Non-invasive methods like acoustic analysis of voice signals can be used to investigate such problems. ...
Electrical properties of fresnoite Ba2TiSi2O8 using impedance spectroscopy
(Trans Tech Publications, 2013)
Fresnoite with composition Ba2TiSi2O8 (B2TS2) was first found in 1965, adopting a non-centrosymmetric structure. It also reported to crystallize in a tetragonal unit cell with a=8.52Å and c=5.210Å leading to some possible ...
Design and simulation of film bulk acoustic wave resonator in kuband
(Trans Tech Publications, 2013)
This paper presents the design of a Film Bulk Acoustic Wave Resonators (FBARs) operating in Ku-band. The one-dimensional (1-D) numerical and the three-dimension (3-D) Finite Element Method (FEM) simulation results are ...
Ferroelectric and relaxor ferroelectric to paralectric transition based on Lead Magnesium Niobate (PMN) materials
(Trans Tech Publications, 2013)
First ferroelectric materials were found in Rochelle salt was in a perovskite structure. Lead Magnesium Niobate (PMN) is a perovskites with a formula of PbMg1/3Nb2/3O3 (PMN) and are typical representatives for most of all ...
