Especially, the lung cancer is the most severe factor of all kinds of cancers. it is mainly removed by video assisted thoracic surgery. However, the lung cancer is estimated visually in the surgery. So, the surgery needs a lot of time and the advance techniques to estimate the cancerous tissue. In this paper, the flat-types of the electrodes have been proposed in order to improve the accuracy of the estimation of the lung position; decrease the burden of the surgery; shorten the surgery time. Our results indicate the possibility of the estimation of the cancer. Using the proposed method, the cancer would be estimated easily. And we will miniaturize the structure of the flat-types of the electrodes and improve the estimation sensibility.","PeriodicalId":283714,"journal":{"name":"2020 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133337319","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}

This architecture is ideal for wearable vital sign sensor, the primary circuits are an SIL tag consisting of an omnidirectional monopole antenna and a frequency selective surface (FSS), and a mobile receiver consisting of a left-hand circularly polarized (LHCP) antenna and a delay discriminator. Worn on the subject's chest, the mobile tag can sense the fluctuations on skins caused by cardiopulmonary activities, and the polarization of the radiating electric field is then converted by the FSS to send an LHCP wave to the remote handheld receiver. Benefiting from polarization diversity, the SIL tag can reject moving clutter in the environment. In the experiments, the 2.4 GHz prototype was not affected by the movement of the handheld receiver or a walking person in the environment. The cardiopulmonary information is still reliable.","PeriodicalId":283714,"journal":{"name":"2020 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129941558","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}

It uses a tail resistor configuration to reduce phase noise with a low supply voltage of 0.7-0.9 V, where a back-gate bias control of the SOTB technology is also employed. An output amplitude of the LC-VCO is designed so as to minimize frequency sensitivity for both current and supply voltage. These lead to a low phase noise of −101 and −123 dBc/Hz at 100 kHz and 1 MHz offset frequencies respectively, with a low power of 0.88 mW. A high-Q LC-tank with low parasitic capacitance design enables a wide FTR of 40.7%, and an excellent figure-of-merit with the FTR (FoMT) of-204 dBc/Hz.","PeriodicalId":283714,"journal":{"name":"2020 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121684459","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}
