For a GNR width of 5nm at 0.275eV band gap, ON current of 1605 μA/μm is calculated with a very high ON/OFF current ratio of 107. Subthreshold slope of 7.07mV/decade is calculated from I-VGS transfer characteristics. Current saturation is observed for input voltage, VGS of 0.28V and beyond for varying VDS values. Performance of the proposed model is compared with the earlier published work and the projected 2011 ITRS MOSFET requirements and it is found that considering proper device geometry and input voltages, GNR T-FET can demonstrate seven times lower power dissipation and eight times higher intrinsic speed in the upper GHz range than in conventional CMOS technology.","PeriodicalId":344851,"journal":{"name":"2013 IEEE International Wireless Symposium (IWS)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123050814","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 antenna array is fed by using two 50Ω coplanar waveguide (CPW) transmission lines with two feeding ports. By placing a central metal strip between two radiating elements, the mutual coupling can be reduced.

Two two-order filters using different resonators are designed to demonstrate the existence and controllability of the common-mode transmission zero. A four-order filter with two resistor-loaded stepped-impedance resonators (SIRs) and two resistor-loaded uniform impedance resonators (UIRs) are designed to get good selectivity of differential-mode passband and wide-band common-mode suppression besides the high CMRR inside the differential-mode passband.
