Assessing the I/O performance delta between dual-referencing and ground-referencing schemes is needed to enable a lower layer count on either board or package, thereby reducing the overall platform cost. Existing methodologies attempted in quantifying impact simultaneously on both PI (Power Integrity) and SI (Signal Integrity) [1], [2] although the work is usually focused on I/O power delivery impact...
The simulation of a double-tunnel junction with the SENS simulator gives access to the frequency-dependent and static behavior of shot noise. The concept of basic paths in a multi-state process provides a clear interpretation of the noise regimes, and allows locating cut-offs in autocorrelation functions and spectral densities.
This paper aims to study the correlation between intuitionistic fuzzy sets obtained as image of intuitionistic fuzzy t-norms and t-conorms. We consider the action of automorphisms and the class of strong fuzzy negations in order to verify the conditions under which the correlation coefficient related to such fuzzy connectives and their corresponding conjugate and dual constructions are obtained. We...
The effect of mechanical stress induced by shallow trench isolation (STI) slope on the data retention characteristics of DRAM is investigated and a new electrical parameter for monitoring the mechanical stress is proposed. To maintain high and uniform retention time for the reliable operation of DRAM, the STI slope should not be vertical and should be kept below 86-degree. The new electrical parameter...
In the existing papers on cooperative diversity, the fading channels are idealistically assumed to be Rayleigh fading channel. Taking into account the realistic propagation environments in the presence of spatial fading correlation, the performance of cooperative protocols using distributed space-time block code (DSTBC) in the two-ring scattering model is analyzed. The time division multiple access...
Polarities of plasma charging damage in n- and p-channel MOSFETs with Hf-based high-k gate stack (HfAlOx/SiO2) were studied for two different plasma sources (Ar-and Cl-based gas mixtures), and found to depend on plasma conditions, in contrast to those with conventional SiO2. For Ar-plasma, which was confirmed to induce a larger charging damage, both n- and p-ch MOSFETs with high-k gate stacks suffer...
Continuous scaling, necessary for enhanced performance and cost reduction, has pushed existing CMOS materials much closer to their intrinsic reliability limits, forcing reliability engineers to get a better understanding of circuit failure. This requires that designers will have to be very careful with phenomena such as high current densities or voltage overshoots. In addition to the reliability issues,...
The field of electronic noses and gas sensing has been developing rapidly since the introduction of the silicon based sensors. There are numerous systems that can detect and indicate the level of a specific gas. We introduce here a system that is low power, small and cheap enough to be used in mobile robotic platforms while still being accurate and reliable enough for confident use. The design is...
In this paper, we propose a robust STBC transmission scheme to combat the timing synchronization errors over frequency-selective multiple-access channels. First, the equivalent channel model in the presence of timing synchronization errors is derived and we find that the synchronization errors result in an equivalent channel model with larger number of correlated channel taps. Based on this correlated...
