The filter consists of a short-ended interdigital coupled-line unit fed by stepped-impedance lines. Through adjusting the stepped-impedance feed lines, an ultra wide passband with equal-ripples can be obtained. The filter also has multiple transmission zeros on both sides of the passband, exhibiting favorable passband skirt property. The filter is fabricated, and its measured results show good agreement with the simulated responses.","PeriodicalId":281858,"journal":{"name":"2014 IEEE International Symposium on Radio-Frequency Integration Technology","volume":"39 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130968605","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}

These transmitters, with their unique specifications such as fast oscillation start-up, fast locking or proper capacitor bank design, require different VCO design considerations. We first look at a fast on-off LC-VCO used to realize OOK IR-UWB transmitter. It is implemented in 0.18μm CMOS process and achieves 2Mbps at 236μW power consumption. Next, we examine injection locking LC-VCO employed to achieve efficient QPSK/O- QPSKB modulation. Through proper capacitor bank design, an EVM of 6.4% has been demonstrated at data rate of 50Mbps with the low reported energy efficiency of 118pJ/bit.
