Indirect calorimetry estimation, based on oxygen and carbon dioxide measurements, is the only way to achieve this result. In this paper a compact yet efficient oxygen sensor is presented as a key component for this application. Ruthenium fluorescence is used as sensing element due to the strong quenching effect in presence of oxygen. An FPGA-based TDC and data retriever have been implemented granting a high degree of freedom in terms of tunability and resolution.","PeriodicalId":403202,"journal":{"name":"CAS 2011 Proceedings (2011 International Semiconductor Conference)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126478743","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}

Proper input matching is achieved with inductive degenerated amplifier circuit modified with resistive feedback. To provide good isolation and stability, cascode amplifier, as a first amplifying stage, is used. Additional common source stage is introduced by using current reuse technique. Operated at 1.8 V LNA consumes only 5.26 mW. The simulation results show maximum power gain of 14.3 dB, while the input and output return loss is less than −10 dB, within the bandwidth from 6 to 8.5 GHz. The noise figure of the LNA varies from 3.9 to 6.8 dB.","PeriodicalId":403202,"journal":{"name":"CAS 2011 Proceedings (2011 International Semiconductor Conference)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126014209","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}
