This paper proposes an output impedance tuning method by using resistive feedback and a parallel resonance consisting of an inductor and a tunable capacitor array.

The PA is implemented by using a 0.18 μm CMOS process, and the supply voltage is 3.3 V. Over all of the frequency range, the PA realizes output return loss S22 of smaller than −10 dB, power gain of larger than 16 dB, output 1-dB compression point of larger than 17 dBm, and power added efficiency (PAE) at 1-dB compression point of larger than 10%.","PeriodicalId":263023,"journal":{"name":"2009 IEEE Asian Solid-State Circuits Conference","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121136217","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 purpose of the linearization technique is to eliminate Gm″ value of the transconductor by employing a superposition method that combines two opposite non-linear behaviors of the two parallel wings designed inside the transconductor. Instead of conventional biquad structure, a resonant-coupling structure is adopted for the band-pass filter working at center frequency of 80MHz to make the frequency response flat and stable and to allow a stable frequency tuning as well as a flexible bandwidth tuning. Fabricated in 65nm CMOS process, the implemented IF band-pass filter provides a flat band-pass whose ripple is smaller than 0.1dB, a third-order rejection of 27dB, an IIP3 of −2dBm, and a NF of 21.5dB, while consuming 11mA from 1.2-V supply.

An XY-coil layout style allows logic interconnections to go through the coil, which significantly saves interconnection resources consumed by the coil. However, the logic interconnections generate capacitive-coupling noise on the coil and degrade signal in the inductive-coupling link. In this paper, an extended XY coil with ground shields is presented for noise reduction. Simulation study shows that the noise voltage is reduced to 1/5 of the conventional XY coil. This noise reduction enables to reduce transmit power required for the same BER. Test-chip measurement in 0.18μm CMOS demonstrates that the transmit power at lGb/s with BER<10-12 is reduced by 60% compared to the conventional XY coil.","PeriodicalId":263023,"journal":{"name":"2009 IEEE Asian Solid-State Circuits Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132833637","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}
