Current proof of concept embodiments at 250MHz and 915MHz have been successful in demonstrating a functional sensor design and working interrogation system. However, previous work has done little to optimize the sensor platform into a single package containing the SAW device, matching network, and antenna. Through the work presented a more ubiquitous sensor network will be achieved by significantly reducing the tag footprint while optimizing device performance. The following will first briefly review the OFC device concept and present current device embodiments at the frequency of interest. An overview of current tag antenna and matching network design is presented next as a basis for the work to follow. Finally, a compact sensor target will be outlined based on optimizing trade-offs in device range and overall tag size.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123469445","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}

Understanding and using this tradeoff is helpful to radar and communication designers and can be used to assist in operating with optimum efficiency while meeting spectral mask requirements instituted by regulatory agencies. In this paper, a simulation-based investigation is performed into implementations with a 180-degree coupler and with a Chireix outphasing network. In general, the overall efficiency in both designs is a function of the amplitude modulation of the message signal in the LINC configuration; however, the 180-degree coupler has a potential to obtain higher linearity in many cases due to the isolation of its two input ports. In certain cases of amplitude modulation, however, much of the output power in the 180-degree coupler design is delivered to an unused termination rather than to the network output.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125493034","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}

Two common-source n-FETs are connected with each other through a coplanar waveguide only, acting as an on-chip inductor. The design uses 3 stages of n-FETs cascade gain cell, with a bias of 1.4V. This oscillator called OSC-1 operates at K-band frequency 18.40G~z with 10.75dbm power level and the phase noise is a record in an industry standard 0.18pim CMOS technology of -126.857dBc/Hz at 1MHz offset from the carrier. A design modification is reported called OSC-1A and with body biasing of n-FETs from -1.5V to 0.6V, the frequency tuning of this 19.47 GHz D-VCO is 1.16 (18.89 - 20.05) GHz with uniform phase noise performances. With supply voltage variation, the OSC-1A frequency of 19.47 GHZ at 1.8V is tunable up to 18.57 GHz at a bias of 0.9V i.e. 900MHz. With different width of n-FETs, this design can be reused for other frequencies like Ku band frequency of 17.74 GHz with 5.07dBm or K-band frequency of 19.81GHz with 2.41dBm at 1.8V operation. A novel design is proposed for third harmonic generation in DO topology with five stages called OSC-TH, 3rd harmonic frequency of 29.27 GHz in Kaband with -0.3dBm power level is reported, whereas the fundamental is of -12.828dBm at 9.756G~z and 2nd harmonics of -17.289dBm.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"337 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115462293","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 advantages of the proposed continuous-time sigma-delta modulators include the fact that it eliminates the need for an anti-aliasing filter in front of the ADC because of its intrinsic anti-alias filtering property. Additionally, the use of weak inversion and a low flicker noise structure minimizes power consumption and low frequency flicker noise. Finally, the decimation filter used in ordinary sigma-delta ADCs to attenuate high-frequency noise is eliminated because the biomedical sensor analyzes the periodogram in software, thus significantly reducing the cost and power consumption. A design example illustrating these advantages is presented in this paper.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115891733","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}
