FEM simulations were performed in order to predict the mechanical behavior of the membrane and of the package. One-port SAW devices having IDTs of 120 nm width were fabricated bye-beam nanolithography. High values of the sensitivity (1102 kHz/Bar) and of the pressure coefficient of frequency (126 ppm/Bar) have been obtained due to the very high frequency operation (8.7 GHz) of the SAW. An insignificant dropping of these values was obtained after the bonding of the capsule.","PeriodicalId":380138,"journal":{"name":"2022 International Semiconductor Conference (CAS)","volume":"25 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115587072","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 performance of the proposed Buck converter was analyzed using pre-silicon simulation results. The most notable aspects/parameters are highlighted by comparison with other implementations. The system has $approx 180 ns$ reaction time and less than $1mu s$ settle time with a $pm 27%$ output ripple variation over temperature and process. The ripple is fairly constant with the $Vo DC$ level that brings a 0.33% to 1.3% variation from 5V to 1.2V. The new controller concept offers more flexibility in choosing the external passive components. The proposed circuit was implemented in an 130nm BCD automotive technology.","PeriodicalId":380138,"journal":{"name":"2022 International Semiconductor Conference (CAS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125510889","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 germanium post-treatment was performed by rapid thermal annealing at 450 and 700° C. The sensors were characterized by X-ray diffraction diffractogram and scanning electron microscopy. It is demonstrated that the sensors are highly sensitive as human breath detectors, with rapid response and frequency detectability.

The method involves the determination of a model for this type of transition which consists of a lossy two-port and two lossless transmission lines. The parameters of the transmission lines can be computed based on simple formulas, while the ABCD matrix of the two-port can be obtained by solving a matrix equation using a commercial software. Two measurements of scattering parameters are performed to develop the proposed model, for thru and short-circuit calibration standards. The phase constant and return-loss for a waveguide section inserted between two coaxial to waveguide transitions are obtained by de-embedding the transitions using the proposed model. The results are in very good agreement with the expected ones.
