During clinical trials, it is important to know with certainty a patient's compliance to a medication regimen, because without it, the results cannot be interpreted accurately. Small antennas printed directly onto the surface of standard capsule can potentially serve as a cost-effective method of validating medication compliance via electronic detection of a swallowed pill in the digestive tract. In this paper, we investigate various aspects of these \"electronics pills,\" including printing methods, conductive inks and radiation characteristics of electrically small antennas inside the human body. We employ realistic antenna models and electromagnetic simulations based on the finite difference time domain method to determine the radiated field intensities for sources in the body. Phantoms solutions with electrical properties that are approximately equivalent to biological tissue are used to experimentally validate simulated results and characterize signal attenuation of electrically small radiation sources in the human torso.","PeriodicalId":273819,"journal":{"name":"2007 IEEE Biomedical Circuits and Systems Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116657381","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}

Choosing a proper system architecture allows to implement a receiver with relaxed specifications for the typical building blocks which results in a low-power implementation. Furthermore a design in 130 nm CMOS of a fully integrated ultra-low power PLL, a critical block of such receivers, is presented. The PLL serves a double purpose. It acts as the master clock generator for the receiver and it is also used to generate a template waveform for pulse reception. The latter requires the PLL to have quadrature outputs since the receiver uses I/Q reception. Because rather relaxed specifications in terms of phase-noise are required, a differential ring VCO with an even amount of stages is a suitable topology. The VCO has a measured center frequency of 568 MHz and a tuning range of 23%. It achieves a phase-noise of -91 dBc/Hz @ 1 MHz offset. The PLL employs a divide-by-8 and locks to an externally applied 75 MHz clock. Measurements show a total power consumption less than 200 muW with an rms jitter of 24 ps on an output clock of 600 MHz.","PeriodicalId":273819,"journal":{"name":"2007 IEEE Biomedical Circuits and Systems Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127066836","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}
