Учет влияния температуры на радиационный сдвиг порогового напряжения МОП-транзистора в системе TCAD
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.
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.
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.
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.
There is considerable international activity in the development of numerical models for the purpose of climate simulation and for forecasting on various timescales. This publication is an attempt to foster an early interchange of information among workers in these areas. The material in the publication is the response to a "call for contributions" sent to scientists worldwide. Contributions obtained in response to this call are included if they are related to the CAS/JSC numerical experimentation programme, if they give new results, and if they are of suitable length and size. Reports that do not meet these criteria, have been previously published, or are purely theoretical may be rejected. The most appropriate reports give results of new numerical experiments in the form of a succinct explanation accompanied by suitable tables and figures. The contributions are collected into subject groupings as appropriate. The range of subjects is expected to vary with time and depends on the submissions received. The large number of contributions from around the world indicates the wide scope of activities in numerical experimentation, and the valuable addition that this type of report makes to the refereed journals. Comments and suggestions for improvement to the publication are welcomed. To facilitate location of specific contributions, they are ordered alphabetically by author in the various subject areas. The publication is web-based and accessible at the WGNE web site at http://bluebook.meteoinfo.ru. Note that since the beginning of 2018 the old link https://www.wcrpclimate.org/WGNE/blue_book.html does not work anymore. For many years the WGNE Blue Book was prepared and edited at the Environment Canada. This multi-year initiative is highly appreciated. Now the Hydrometcentre of Russia has taken the lead on the activity. In 2016-2017, the contributions to the WGNE Blue Book were submitted through the web site of the Hydrometcenter of Russia. Recently a new web site of the Working group of numerical experimentation http://wgne.meteoinfo.ru has been developed. The site is currently supported by the Hydrometcenter of Russia. Since 2018, the contributions to the WGNE Blue book are submitted through the new WGNE site at http://bluebook.meteoinfo.ru/add_article.php.
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 possibilities of commercial SPICE are expanded in the new field—space environment electronics design. For this purpose, the set of BJT and MOSFET models with account for radiation influence is included into commercial SPICE device library. The characteristics of devices and circuits subjected to space radiation exposure (gamma-rays, protons, neutrons, electrons, heavy ions) are presented and examined with emphasis on application for radiation hardened electronics systems.
An efficient methodology of electro-thermal design of smart power semiconductor
devices and ICs, based on the combined use of SPICE circuit analysis tool and software tools for
2D/3D thermal simulation of IC chip construction, is presented. The features of low, medium and
high power elements, temperature sensors, IC chips simulation are considered
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
