The frontend equalizers operate at high frequencies by employing energy-efficient current integration and resonant clocking techniques. The baud-rate clock-and-data-recovery (CDR) is implemented to reduce the number of samplers and clock phases for the CDR operation. In addition to the design techniques, the generator-based design methodology [4] [5] is utilized to extremely optimize the sizing parameters of critical circuits by automatically generating their layouts and capturing the layout dependent effects. Two representative design examples that used the proposed techniques achieved 60 Gb/s and 15 Gb/s respectively, which demonstrate their effectiveness to achieve such high data-rates with excellent energy efficiencies.","PeriodicalId":113802,"journal":{"name":"2019 International SoC Design Conference (ISOCC)","volume":"98 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128350879","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}

To analyze the performance of each player, the proposed device uses the global navigation satellite system (GNSS) assisted by the inertial measurement unit (IMU). Several algorithms are realized on the embedded processor to estimate the amount of speed, total distance covered, and inertia. In addition, the Bluetooth Low Energy (BLE) protocol is used to transfer acquired data from the pitch while reducing the overall power consumption. Experimental results show that the BLE-based wearable device successfully demonstrates the real-time tracking operation, achieving the low-power solution compared to the existing devices.","PeriodicalId":113802,"journal":{"name":"2019 International SoC Design Conference (ISOCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130684140","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}

That is Neural Network (NN), and it has been focused nowadays.

Traditionally, MTNCL circuits implemented using complementary metal oxide semiconductor (CMOS) technique that tends to occupy a large area. To address this limitation, a gate diffusion input (GDI) methodology is introduced for implementing MTNCL circuits. This GDI technique enables complex logic to be implemented using only two transistors that helps to reduce area utilization. In this paper, a novel approach to implement MTNCL designs based GDI methodology is proposed. The proposed approach has been verified by implementing TH23 MTNCL gate. Comparing to the conventional CMOS implementation, the proposed approach shows a 45% reduction in the area overhead.","PeriodicalId":113802,"journal":{"name":"2019 International SoC Design Conference (ISOCC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129570940","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}
