Active filter design using FBAR allows realizing of a wider range of characteristics. The FBAR active filter design process is related with the optimization of multiple parameters including filter architecture, biasing of active elements, impedance matching and also the topology and structure of resonators. Obtaining of filter's frequency characteristics with high selectivity and smooth phase response is only possible using high-precision models of resonators. The purpose of this work is to propose a three-dimensional finite element model (FEM) of a FBAR for further integration into the computer-aided filter design system. The simulation results of the proposed solution are compared with a frequently used modified Butterworth-Van-Dyke (mBVD) model to designate the significance of changes in the output filter characteristics arising from the application of 3D piezoelectric resonator model.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121277936","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 resistive layer dimensions have been reduced and its small thickness is dependant by the technological manufacturing process, therefore transient electrical events like Electrostatic Discharge Pulses (ESD) can change the initial properties of the resistive layer, which leads to a modification of the resistance value or damaging the layer, causing chip resistor failure. This paper presents an analysis for the thermal and electrical behavior of thick and thin film chip resistors, by applying DC- current and rectangular pulses of short width and high voltage and current amplitudes. These high power and short duration pulses give in situ information about the adiabatic behavior of the analyzed layer.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126111125","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}

We achieved a temperature resolution of 0.2 K and an accuracy of ± 2 K, which correspond to a spectral resolution of 1 pm and an accuracy of ± 11 pm.

The samples were formed on glass substrates, the thermodynamic analysis was carried out by the force 0.3 ±0.2 N at 1Hz, the maximum temperature was 140 °C. It was found that there are no significant differences between the thermodynamic parameters of adhesives tested. It was also found that all adhesives were not optimally cured though curing was carried out in accordance with recommendation of a producer of adhesives.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115971008","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 presents the results of experimental determinations of these properties for several materials (Aluminium, Melamine Faced Fiberboard, and Gypsum Drywall slabs) in a semi-anechoic chamber, at several frequencies, in the band from 2.00 to 3.00 GHz. The results show that aluminum is a good reflector, which was expected, but that melamine hardboard reflects EMW nearly as well as aluminum. The material used for drywall is less reflective at almost all frequencies. The results also show a fairly significant dependence of reflection properties on frequency, as reflected power decreases with frequency.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126703757","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}
