A novel transmitting solution is adopted to realize a low-power and low-complexity physical implementation for future high data rate wireless component interconnect and implantable electronic applications. A UWB PA with standby, a digital ring on-off VCO, a subtractor for eliminating base-band component from the output of the VCO, and a narrow pulse generator are employed to achieve the chip with the maximum data-rate of 200Mbps, tunable-band of licensed 3∼7GHz, low-power of 8pJ/bit, and a small circuit area of 0.2mm2, of which the proposed subtractor, VCO, and PA play the important roles in reducing power dissipation. The simulation results verify that the proposed design is suitable for future potential applications.","PeriodicalId":6363,"journal":{"name":"2011 IEEE International Conference of Electron Devices and Solid-State Circuits","volume":"445 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2011-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75806559","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}

On the other hand, further increasing the Ar/O2 ratio to 4:3 is found to degrade the device performance.
