Combining a third order filter with the class A/B conditioner results in a reduction of both current consumption and RX-band noise injection.

Area-efficient sequential square calculation and a minimization algorithm of the clock number necessary for the search are applied for practical efficiency. Experimental concept verification was done with an 180nm CMOS design implementing 32 reference vectors with 16 components and 8 bit per component. The fabricated test chips achieved 1.19μs average search time, 5.77 μs worst-case search time and low power dissipation of 8.75mW at 47MHz and Vdd=1.8V for code-book-based picture compression. To our best knowledge this is the first report of practical, word-parallel, digital nearest ED-search architecture.

This is achieved through a fractional frequency translation by means of a programmable fractional divider realized as a dynamic edge selector of eight oscillator phases. This way, the integer harmonic frequency relationship of victims/aggressors within and between the RF transmission channels is avoided, thus rendered harmless in the creation of injection pulling spurs. The proposed method can push the injection pulling spurs far away from the carrier and at an infinitesimal power level below -80 dBc. The pulling mitigation for two RF channels has been verified in a 65-nm CMOS testchip that occupies 0.56×1.46 mm2 area and emits -156 dBc/Hz noise floor. An RF oscillator is realized as a class-C topology without tail current source.","PeriodicalId":183620,"journal":{"name":"2013 Proceedings of the ESSCIRC (ESSCIRC)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117321566","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}
