In order to do this, the advantages of a 3D-printed electronics manufacturing process developed in former work demonstrated the usability of helical-microstrip transmission lines and allowed the materialization of a new folded topology for hybrid couplers. The design methodology and the manufacturing process have been described. A conventional hybrid coupler has been also designed, manufactured and characterized in order to compare dimensions and model simulation and prototype characterization results in terms of the scattering parameters.","PeriodicalId":186963,"journal":{"name":"2020 XXXV Conference on Design of Circuits and Integrated Systems (DCIS)","volume":"32 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127375288","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 inclusion of this type of sensors is key in high sensing-demanding applications, such as those based on affective computing. This sensing integration must be quantitatively supported by metrics that directly affect performance, such as processing time, memory usage, and measurement accuracy. This paper presents a comprehensive analysis of a specific smart sensor integration in a wearable constrained device from an embedded perspective. The authors performed this implementation by considering BINDI, which is a wearable device developed by the UC3M4Safety research group to prevent gender violence situations. BINDI monitors user physiological and physical variables to detect fear through artificial intelligence algorithms. Along with other sensors, this device incorporates an electroDermal activity (EDA) sensor. This type of sensor was proven to be a valuable source of information directly related to the autonomous nervous system (ANS) activation, which regulates physiological responses in stress and relaxed affective states. In the initial version of BINDI, which was validated in different experiments with different volunteers, the EDA sensor is based on a DC measurement schema. However, AC measurement EDA circuitry is known to provide a higher amount of information. Thus, this work presents a detailed comparison between the current EDA sensor and a specific AC smart EDA sensor for a future version of BINDI.","PeriodicalId":186963,"journal":{"name":"2020 XXXV Conference on Design of Circuits and Integrated Systems (DCIS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123586763","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}

Therefore, very complex devices are being built which implies a concern in system dependability, especially when critical applications are the objective. In this paper, an enhanced methodology to assess in-field dependability of wearable devices is proposed. It includes a power consumption effect analysis of the mitigation and detection techniques.

In the proposed circuit configuration no resistor nor capacitor are included and only normal CMOS devices with low device count (only three devices) are used. In this manner the active area of the circuit is extremely reduced. The circuit shows a very fast reaction time of less than 2µs that makes it attractive for many real time applications. The proposed circuit has the feature of acting as a composite transistor in the normal active mode of the targeted self biased circuit helping to improve its line regulation performance. This is a benefit of the proposed start-up circuit which is completely in line with the purpose of using the self- biased configurations in voltage reference circuits. The circuit is designed and simulated in a commercial 40nm technology using Cadence tools. The parasitic effects of the layout are also included in the simulations.","PeriodicalId":186963,"journal":{"name":"2020 XXXV Conference on Design of Circuits and Integrated Systems (DCIS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126822845","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}
