2020 26th International Workshop on Thermal Investigations of ICs and Systems (THERMINIC)
The 26th THERMINIC Workshop will be held in Berlin, the capital of Germany. THERMINIC is the major European Workshop related to thermal issues in electronic components and systems. For academics and industrialists involved in both micro and power electronics this annual event promises to be a very special occasion with a high quality technical programme and exciting social events.
Multi-chip embedded PCBs were in resent years the mainstream technology of electronic packaging size reduction and at the same time providing improved performance. Ultra-small package size obviously strongly impacts the SiP module thermal behaviour. Unfortunately the complete thermal design methodology was not developed for this technology till now. In this work the problem of thermal design is completely solved using quasi-3D approach taking into account the main features of embedded PCB constructions: 1) 3D integration of ICs and board; 2) a large number of thinned layers of different materials; 3) vertical z-axis interconnections through the package layers. A ten times decrease of central processing unit (CPU) time is achieved as compared with the full 3D solutions obtained by commercial universal 3D simulators, while saving the sufficient accuracy. The simulation error of maximal temperature T MAX determination for different types of packages is not more than 10-20%.
A set of modified compact SPICE models of various flavours of MOSFETs (fabricated by bulk, SOI and SOS technologies) is presented for circuit simulation in the deep-cryogenic temperature range down to 4 K, which is important for space applications and development of scalable quantum computers. All models are constructed using the approach combining macromodeling based on the standard models available in the library of SPICE models and introducing smooth analytical functions continuous with temperature for the model parameters. A unified automated procedure for model parameter extraction is presented for all the models, providing an acceptable accuracy of accounting for electrical and temperature effects for practical applications in the temperature range from room temperature to 4 K.
The monograph presents results by professor Dr. A. Shalumov’s Research School of Modeling, Information Technology and Automated Systems (Russia). The program, ASONIKA, developed by the school is reviewed here regarding reliability and quality of devices for simulation of electronics and chips during harmonic and random vibration, single and multiple impacts, linear acceleration and acoustic noise, and steady-state and transient thermal effects. Calculations are done for thermal stress during changes in temperature and power in time. Calculations are done for number of cycles to fatigue failure under mechanical loads as well as under cyclic thermal effects. Simulation results for reliability analysis are taken into account. Models, software interface, and simulation examples are presented.
For engineers and scientists involved in design automation of electronics.
AMT 2013 is the most comprehensive conference focused on the various aspects of advances in Advanced Measurement and Test. The conference provides a chance for academic and industry professionals to discuss recent progress in the area of Advanced Measurement and Test. The goal of AMT2013 is to bring together the researchers from academia and industry as well as practitioners to share ideas, problems and solutions relating to the multifaceted aspects of Advanced Measurement and Test.
Negative pressure also means negative energy and, therefore, “holes”, antiparticles. Continuation across infinity to negative energies is accomplished by using a parastatistical correction to the Bose-Einstein distribution.
This paper is an analysis of lexical categorisation of the temperature domain in modern Eastern Armenian. Compared to the vast research outline proposed in (Koptjevskaja-Tamm 2011), this paper has several important limitations. First, it is focused on non-derived, primary temperature terms (most of which happen to be adjectives or nouns, or both). Derived lexical items, as well as lexical items that apply to temperature phenomena only secondarily, are not considered. Second, it focuses on lexical rather than morphosyntactic categorisation, in the sense that more attention is paid, again, to lexical items than to the morphosyntactic patterns they are associated with. In a sense, we focus on elementary morphological units – dedicated temperature roots – rather than on the morphological and morphosyntactic patterns they are involved in.
As Eastern Armenian represents an elaborated system of temperature terms (some dozen lexical items), even under such restrictions the linguistic data presented below is well worth of analysis. To a certain extent, the issues of part-of-speech derivation are brought into consideration. It should also be noted that, as the examples in the paper show, there seem to be no sharp differences between e.g. morphosyntactic treatment of the subjects of tactile vs. ambient vs. personal temperatures, such as shown in Koptjevskaja-Tamm (2011) through a comparison of French, Finnish, Japanese and German examples. It is true that, as in many languages, in Armenian ambient temperature is often expressed by impersonal predication (cf. ex. 3 below). However, experiencers of personal temperature (as most experiencers in general), carriers of tactile temperature and meteorological phenomena expressed by explicit NPs (‘day’, ‘air’, ‘sun’) predicated by ambient terms are all treated as subjects. They are assigned nominative marking and control verbal agreement. There certainly may be finer morphosyntactic differences, but these are left for future research(ers).
The structure of the paper is as follows. Section 1 provides a brief genealogical, structural, sociolinguistic and historical account of the Eastern Armenian language and introduces the main source of the present study (Eastern Armenian National Corpus). Section 2 provides an overview of the temperature words of Eastern Armenian along the lines of the typological dimensions around which the present volume is centred, including the pivotal distinction between tactile and ambient temperatures. Personal temperature terms are in a sense independent from this main opposition, so that the discussion of personal temperatures goes alongside but apart from the main argument, both here and later in Section 6. Section 3 is an overview of metaphorical uses of the temperature terms. Section 4 considers part-of-speech properties and some aspects of derivational morphology of the Eastern Armenian temperature words. Section 5 is an account of the known etymologies of the terms. Section 6 introduces some data on relative textual frequencies of temperature terms. Section 7 is a summary of the paper.
For the correct accounting of joint effects of radiation and temperature on characteristics of MOSFETs with the help of TCAD system the nonlinear correction coefficient which considers change of concentration of traps from temperature is entered into model of traps volume density in oxide.
Pressure sensors on the basis of thin-film tenzorezistorny nano – and microelectromechanical systems with the frequency output signal, steady to influence of temperatures are considered. Original schemes of frequency converters and topology of an arrangement of tenzoelement on a membrane of a sensitive element of the sensor are submitted.
Optimization of designing radio electronic equipment by criterions of temperature and reliability decrease time for creation the new radio electronic equipment, increase reliability of it and decrease expenditures during elementary stages of designing because designers have possibility to choose version of scheme and construction which ensure minimum temperatures of element base in conditions of exsploitation.
The project of laboratory practical works for studying of different electronic devices based on microcircuits of operational amplifiers was developed.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
