The noise and sensitivity of a harmonic radar system, which is developed at 12 GHz and 24 GHz for vital signs detection, are studied numerically and experimentally. The received signal power of the radar system is analyzed numerically as a function of the distance, taking into account the radar cross section (RCS) of the patient chest. The numerical data are compared with results obtained with single carrier frequency system. The total noise is a combination of thermal noise, residual phase noise, and flicker noise that presents the most elevated factor influencing the detection at baseband. Experimental results show that with the harmonic radar, the flicker noise can be reduced by 20dB at around 1Hz baseband frequency.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"127 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85111824","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 sensor is based on a resonant microstrip ring with a microfluidic container placed on top. The interaction between the electric field and the milliliter range water-glucose solutions under test can be observed measuring the phase shift of the S-parameter from 3.98 to 4.05 GHz. Combining the microwave detection and the microfluidic network, a time efficient and low cost architecture is presented.

To address these needs, this work presents an injection locked clock and data recovery (CDR) circuit in 65 nm CMOS for body channel communication transceivers that employ direct digital transmission. The CDR utilizes pulses generated due to the high pass nature of body channel from transmitted digital data and injects them directly into the VCO to recover the clock. The injection locking achieves instantaneous clock and data recovery compared to conventional PLL based CDR circuits for data rate of 100 Mb/s. With a low power consumption of 0.36 mW and a small footprint of 0.07 mm2, the proposed CDR helps further miniaturization of battery operated biomedical ICs.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"44 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88307473","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 resolution of microwave image is dominated by the bandwidth of microwave signal; whereas, the contrast depends on the signal to noise ratio (SNR) - the higher the SNR is, the better the contrast of the images is. In general the wider the bandwidth of a signal has, the higher the frequency will be, which in turn causes more serious attenuation during wave propagation inside tissues. The resulting SNR is then degraded. Thereby, there is a tradeoff between the resolution and contrast of microwave images. This paper intends to study the tradeoff of the high quality microwave imaging based on a new communication scheme. In particular, we consider an multiple-input multiple-output (MIMO) approach for breast tumor detection. Conducted computer simulations show that this scheme can get a better target identification capability and improved SNR and that it can attain a better tradeoff between resolution and penetration depth.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"116 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74815026","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}

Thorough survey and analysis of patient and physician use cases is critical for steering the design and development phases to maximize a product's chance of success.
