We find approximate analytical solutions to the problem of cooling a silicon detector ladder which is internally heated by leakage current caused by radiation damage. The heat generation term has an approximately exponential temperature dependence. Heat is removed by convection and / or conduction to a heat sink. Design equations are derived which prevent thermal runaway, and a wide range of pa...

In the paper the analytical evaluation of the uncertainty on signal parameter estimation in frequency domain is dealt with. Two different and widely diffused algorithms able to compensate the spectral leakage effects due to asynchronous sampling are considered. The combined uncertainties on the final results (tones frequency, amplitude, and phase) due to the propagation of the uncertainty on th...

We report detailed current-transport studies of ultrathin Al2O3 dielectrics on GaAs grown by atomic layer deposition (ALD) as a function of film thickness, ambient temperature and electric field. The leakage current in ultrathin Al2O3 on GaAs is comparable to or even lower than that of the state-of-the-art SiO2 on Si, not counting on high dielectric constant for Al2O3. By measuring leakage curr...

The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure multi-segment gate (MSG) CNTFET. Band to ...

As VLSI technology continues to scale, parameter variation is about to pose a major challenge to high-performance processor design. In particular, within-die variation is directly detrimental to a processor’s frequency and leakage power. To gain an understanding of this problem, this paper starts out by proposing a microarchitecture-aware model for parameter variation. It includes both random a...

Security of information flow is commonly understood as preventing any information leakage, regardless of how grave or harmless consequences the leakage can have. Even in models where each piece of information is classified as either sensitive or insensitive, the classification is “hardwired” and given as a parameter of the analysis, rather than derived from more fundamental features of the syst...

The transcapillary escape rate of albumin (TERalb), i.e., the fraction of intravascular albumin mass passing to the extravascular space per unit time, is a parameter of the leakage of macromolecules from the total microvasculature. In patients with psoriasis short-term PUVA treatment induces an increase in TERalb. In this study TERalb was measured in 3 groups of normal humans treated with PUVA,...

In this study, we investigate the degradation characteristics of E-mode GaN High Electron Mobility Transistors (HEMTs) with a p-GaN gate by designed pulsed and prolonged negative (VGS) bias stress. Device transfer transconductance, output, gate-leakage were studied in detail, before after each VGS We found that gradual electrical parameters, such as threshold voltage (VTH) shift, on-state resis...

As device sizes continue to shrink and circuit complexity continues to grow, power has become the limiting factor in today’s processor design. Since the power dissipation is a function of many variables with uncertainty, the most accurate representation of chip power or macro power is a statistical distribution subject to process and workload variation, instead of a single number for the averag...

In this paper an adaptive law with leakage is presented. This law can be used in the consequent part of Takagi–Sugeno-based control. The approach enables easy implementation in the control systems with evolving antecedent part. This combination results in a high-performance and robust control of nonlinear and slowly varying systems. It is shown in the paper that the proposed adaptive law is a n...
