A constrained least square fit of the thermal response of a parametric dynamic compact thermal model, having as parameters the material thermal properties and geometrical details to be calibrated, onto the measured temperature response is performed. Numerical results show that the use of parametric dynamic compact thermal models instead of detailed compact thermal models, in conjunction with an optimization algorithm solving the constrained least square problem, can reduce the computational time for calibration by more than two orders of magnitude.","PeriodicalId":143150,"journal":{"name":"2016 22nd International Workshop on Thermal Investigations of ICs and Systems (THERMINIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116494012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extensive research had been conducted to reveal the distinct transport behaviour for charge carriers, however, novel investigations have shown that heat carriers (i.e. phonons) are also subject to new transport phenomena. In the study, we estimated possible propagation modes for the dual phase lag model proposed by Anderson and Tamma with additional boundary effects on propagation of heat carriers in a nanoscale silicon layer. Furthermore, if the heat conductivity coefficient's dependence of size (via Knudsen-number) is taken into consideration then the A-T model predicts new ballistic transport mode along the well-known diffusive behaviour. We were able to confirm the existence of new transport modes for heat carriers in nanoscale systems theoretically. The results are not only important from a physical perspective but can be a ground for several technical developments where heating and cooling of the material is crucial (e.g. microprocessors).","PeriodicalId":143150,"journal":{"name":"2016 22nd International Workshop on Thermal Investigations of ICs and Systems (THERMINIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127974086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper considers the steps needed to model inductors for such optimisation techniques. The use of multi-domain methods to combine smaller component models into a larger system model is the first step for such virtual prototyping. For the modelling of the electrical performance of components, Partial Element Equivalent Circuit (PEEC) models have been used. Standard PEEC techniques, however, are not able to model magnetic components. The extension of these methods to incorporate magnetic materials allows for the modelling of inductors using these techniques. Model Order Reduction (MOR) techniques applied to the system matrices produced by PEEC allow for solving transient models quickly without loss of model fidelity. With all three of these techniques, combined rapid virtual prototyping of systems including inductors is possible.","PeriodicalId":143150,"journal":{"name":"2016 22nd International Workshop on Thermal Investigations of ICs and Systems (THERMINIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128662318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigations are based on a practical example of a circuit containing a bipolar transistor heat source. Its temperature is measured using the base-emitter junction. Additionally, infrared measurements of circuit surface temperature are taken. The measurements are carried out in a wind tunnel for different values of dissipated power and with variable cooling air speed. The measurement results are analysed allowing the assessment of heat transfer coefficient variation with surface temperature and cooling air velocity. Based on the analyses, compact thermal models are generated for the circuit allowing fast and accurate simulation of circuit temperature in various cooling conditions.","PeriodicalId":143150,"journal":{"name":"2016 22nd International Workshop on Thermal Investigations of ICs and Systems (THERMINIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126665801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
