The vital signs detection radar sensor system consists of a transmitter and a receiver. This system can be considered as a wireless system. In the wireless system, the outage probability is a crucial factor to evaluate the reliability of the system. This work investigates the outage probability (OP) of a radar sensor system under the Nakagami-m environment. The dependence of the OP on different parameters like operating frequency, distance to the measured object, transmitter power, and the leakage between transmitter and receiver antennae is examined. The theoretical model for the OP is validated with simulation results through various environments.","PeriodicalId":181015,"journal":{"name":"2018 12th International Conference on Sensing Technology (ICST)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131979135","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 designed accelerometer consists of a MEMS based acceleration sensor and an analog readout circuit with continuous time feedback. The interfacing circuit for the closed loop accelerometer is designed using SCL 180 nm CMOS process technology. A PI controller has been incorporated in the design to improve the stability of the accelerometer. To ensure the operation of the accelerometer, an equivalent model for closed loop accelerometer is implemented using Cadence Analog Design Environment and the complete system is simulated. Although the complete interface uses a 1.8V supply voltage, to provide the necessary actuation to the accelerometer, the feedback amplifier works with a 3.3V supply voltage. The change in the supply voltage enables the accelerometer to function in a closed loop and also improves the range of accelerometer. The closed-loop accelerometer is designed for an input range of ±1g.","PeriodicalId":181015,"journal":{"name":"2018 12th International Conference on Sensing Technology (ICST)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121029372","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}
