It has a compact size with the overall dimensioning of 54×18× 8 mm3, in which can be simply concealed within mobile handsets. Techniques such as meandered lines are used in order to accomplish a well-matching and size reduction of antenna. The meander lines were printed on FR4 substrate with relative permittivity of 4.4 and dielectric loss tangent of 0.0017 with a thickness of 1.6 mm. The results of the present design structure were checked in terms of reflection coefficient, operational bandwidth, current surface, and radiation pattern characteristics. The results have shown that the proposed design can be an attractive candidate for use in mobile handset.","PeriodicalId":441203,"journal":{"name":"2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116712378","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 proposed yield estimation technique reduces the number of required MC simulations during the optimization process.

In order to address this problem, a new framework to ease reuse-centric bottom-up design of analog integrated circuits is introduced. Our IIP Framework (IIP: Intelligent Intellectual Property) enables the development of highly technology-independent analog circuit generators applicable in multiple design environments. IIP Generators are parameterizable descriptions of each view of an analog block, i.e., layout, schematic, and symbol. They allow the adaptation of complex layouts within seconds to minutes in order to incorporate hardly estimable parasitics and further considerations into the design flow. Due to the abstract generator description, valid design data is created for very different technologies such as 28 nm and 180 nm bulk CMOS, 28 nm FD-SOI, and others. The design experiment shows that procedural generators can be an effective tool for the efficient design of analog integrated circuits.","PeriodicalId":441203,"journal":{"name":"2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"73 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113992509","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}

Wavelets can be used for modeling complex parts of microwave circuits, such as cavity resonators.

Using wavelet analysis offers the possibility of systematic and adaptive refinement, where the result is not sufficiently precise.

After studying the analytic solution and the simulation results of a circuit utilizing a pulse-with-modulation scheme it was found, that the switching intervals form adequate time-steps. To prove this, a basic simulation software was implemented and several simulations were conducted. Finally, the simulation accuracy was improved by introducing additional time-steps and impact on the convergence speed and memory consumption was studied.","PeriodicalId":441203,"journal":{"name":"2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125567729","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}

These detectors are expensive to assembly and the bump size limits the minimum pixel size. In order to overcome those limitations full monolithic pixels are being investigated. The idea is to integrate into the same chip the sensor matrix and the readout electronics. Simultaneously, new methods for measuring the energy of the detected particles with higher precision that those achievable by using the Time Over Threshold (TOT) technique are under study. This paper presents a behavioral model of the preamplifier stage of a pixel readout channel written in Verilog-A. The purpose of this model is to allow studying different solutions for measuring the energy with higher precision without the need to design the readout channel at transistor level. The presented model is very simple and written as a function of the main parameters of the pre-amplifier stage, that is, open loop gain, bandwidth, coupling capacitor, and feedback capacitor.","PeriodicalId":441203,"journal":{"name":"2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123116007","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}
