Monolithic integration of out-of-plane Au inductors with Complementary Metal-Oxide-Semiconductor (CMOS) LC oscillators is reported in this paper. The recently developed self-assembly process involves in-plane fabrication of Au inductors and subsequent rotation of the structure by surface tension forces of a melting Sn hinge. The CMOS compatibility of this process is demonstrated through the integration of an LC oscillator with the self-assembled inductor using post-CMOS processing. At a 1.48 GHz oscillation frequency, a phase noise of −95 dBc/Hz is reported at a 100 kHz frequency offset. Obtained results show this technique to be promising for the integration of high Q inductors with commercial RF systems.","PeriodicalId":148226,"journal":{"name":"2009 European Microwave Integrated Circuits Conference (EuMIC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131503936","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 filter is designed for operation in X and Ku bands with 4 pre-selected centre frequencies (from 10 GHz to 14 GHz) and with a bandwidth tunability of 70% (variable between 500 MHz and 1 GHz). The filter originally includes a fine frequency tuning to correct the centre frequency position that slightly and intrinsically shifts when tuning the bandwidth.

Flip-chip is a promising candidate to meet requirements like low reflections, low insertion loss and low costs for mm-wave applications. This paper addresses the design, modeling and evaluation results of a 60GHz LC-VCO module using flip-chip. The impact of the substrate on on-chip CPW transmission lines and spiral inductors is studied based on the performance of a 60GHz LC-VCO. Since the inductor is part of the VCO resonator, a remarkable 10% increase in oscillation frequency occurs due to the nearby top-metal layer of the substrate. The IC is realized in a 0.25µm SiGe BiCMOS process. The 0.44mm thick substrate offers four copper signal layers.","PeriodicalId":148226,"journal":{"name":"2009 European Microwave Integrated Circuits Conference (EuMIC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116812779","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 model is used to explain the bias- and terminal-potential dependency of the turn-on transients and their time constants. Because the time constants are extremely long they impact the measurement of true dc characteristics and contribute to knee walk-out. Temperature as a function of time is shown to be a vital consideration. The models of both drain current and trapping need to consider temperature and power dissipation versus time. The relationship between trap potentials and terminal potentials is investigated.","PeriodicalId":148226,"journal":{"name":"2009 European Microwave Integrated Circuits Conference (EuMIC)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115530810","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 method allows a really fast CAD analysis both in DC and RF periodic regime especially when global modeling is required.

Such sources, radiated from cell phones, radio transmitters and Wi-Fi equipments, are ubiquitously available but have very low power densities, at different frequency bands, with unknown directions of incidence and polarization. In order to harvest a significant quantity of energy it is mandatory to put a very special care in the design of each part of the receiving/storing system. For this purpose a combination of resonant antennas, each one designed for a specific application-dependent frequency band, is optimised together with the rectifying circuit and the load. This is accomplished by a rigorous design tool, based on the concurrent use of nonlinear and electromagnetic CAD methods. Multi-source non linear simulation of the harvester in realistic operating conditions predicts a DC power of a few hundred μW, which represents the typical energy requirement of a sensor node.","PeriodicalId":148226,"journal":{"name":"2009 European Microwave Integrated Circuits Conference (EuMIC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128887453","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}
