We introduce a first order linear model of an LC QVCO at millimeter wave frequencies and derive the oscillator steady-state parameters. Varactor size optimization for maximum quality factor at millimeter wave frequencies is thoroughly analyzed. To overcome the classical tradeoff between the varactor quality factor and tuning range, we suggest an alternative wide-band linear frequency tuning technique based on the fundamental operation of LC QVCOs. By changing the bias of the coupling transistors (GMc-tuning), a wide frequency tuning range of 5 GHz (57.5 GHz rarr 62.5 GHz) can be achieved with very linear characteristics. The GMc-tuning technique exhibits 4 dBc/Hz lower phase noise than a varactor solution. The circuit draws a maximum of 17.6 mA (excluding buffer circuits) from a 1 V supply.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132546172","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 anticipated presentation will cover the current status and future trends of millimeter-wave MMICs, including those using III-V compound (GaAs, InP, GaN, etc.) and Si-based (CMOS, SiGe HBT and BiCMOS) MMIC technologies. Millimeter-wave MMICs used to be applied to military and astronomy systems for long time and started to be utilized for civil applications in the decade, such as communications and automotive radars. The evolution of IC technologies has enabled the performance of Si-based MMICs over 100 GHz, even in standard bulk CMOS processes. This is believed to have a major impact in the future development of millimeter-wave systems. Since low-cost mass-production potential pushes forward the technology, a very high integration of circuit functions on a chip, such as RF, base-band circuitry, automatic-control for a steady operation, and maybe even the antenna, etc. should be included, and thus the system on chip (SOC) issues should be addressed, especially in MMW regime. Moreover, millimeter-wave packaging cost always dominated in the module development In order to simplify the assembly and reduced cost, the concept of system in package (SIP) has been proposed. This presentation will also survey the current technologies for SOC and SIP and discuss related issues and challenges.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114760528","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}

Heterodyne interferometric measurements are performed on beam and plate resonators obtained using the silicon-on-nothing (SoN) process. We obtained respectively 6.6 and 10.5 MHz resonant frequency for these devices, in correlation with ANSYS simulation predictions. Dynamic optical characterization seems to be a promising method to study nanoelectromechanical devices in the aim to enhance their performances.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"428 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122824932","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 die area was significantly reduced by replacing the multi-oscillator solution used at present with a single high frequency Colpitts oscillator, followed by a ratiometric frequency divider that generates the local oscillator signals for the entire satellite TV L-band. VCO pulling was reduced by having a larger frequency offset between the two PLLs, while the ADC spurs were avoided by performing a dynamic clock frequency management. The DC offset cancellation loop capacitors were integrated onchip by combining a multiple loop architecture with Miller capacitance multiplication. Tuner specifications include: -85dBm sensitivity, <7dB noise figure, +26dBm IIP3 at minimum gain,<0.7° total integrated phase noise, 24mm2 die area and 2W power from a 3.3V supply in dual channel reception mode.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127757893","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}

Several architectures such as single gate, FinFETs (double gate), triple-gate represented by Pi-gate MOSFETs are simulated and compared in terms of channel and fringing capacitances for the same occupied die area. Simulations highlight the great impact of diminishing the spacing between fins for MuGFETs and the trade-off between the reduction of parasitic source and drain resistances and the increase of fringing capacitances when selective epitaxial growth (SEG) technology is introduced. The impact of these technological solutions on the transistor cut-off frequencies is also discussed.","PeriodicalId":350325,"journal":{"name":"2008 IEEE Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127420522","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}
