These parameters include the effect of Fluorine-doped Tin Oxide (FTO) etching, FTO cleaning, the number of compact TiO2 (c-TiO2) layer, the number of mesoporous TiO2 (m-TiO2) layers and the aging time before Ag deposition. Our results demonstrated that etching of FTO substrate with Zn/HCl is an essential step and has a major effect on the solar cell's open circuit voltage (Voc), fill factor (FF) and power conversion efficiency (PCE). Furthermore, we demonstrate new and improved protocols for the complete cleaning of FTO substrates. Despite the use of sonication and plasma etching in previous cleaning techniques, SEM images clearly show black clouds in the samples, which may be due to residual Zn particles in the FTO grooves. Thus, a soft toothbrush was used with detergent before sonication to detach the remaining Zn particles. In addition, the optimum number of spin coated layers of compact and mesoporous TiO2 precursors was investigated. We found that one mesoporous and two compact TiO2 layers were required to obtain a homogenous pinhole-free compact layer. Consequently, we demonstrate that using these optimized device fabrication procedures, a high efficiency of 17.96% for 6 mol% Co3+-doped TiO2 solar cells can be obtained in comparison to 16.98% for pristine TiO2-based cells. Such cells are particularly important for wearable applications that require a small area and a high energy.","PeriodicalId":404022,"journal":{"name":"2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129516046","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}

SSD is a distortion metric of the motion estimation in the High-Efficiency Video Coding (HEVC) standard. Distortion metrics are the most time-consuming operations of the encoder. SSD hardware architecture consists of a sum tree that accumulates the calculation of the partial values. The addition tree in the SSD opens an opportunity of exploring efficient addition schemes such as the combinations of efficient adder compressors. The SSD architectures herein presented are compared regarding power dissipation using real video sequences. Our work overcomes the state-of-the-art related work which they investigated different SSD hardware architectures concluding that employing the synthesis tool arithmetic operators are the best choice to reduce the power dissipation. According to our results, we reveal that the SSD employing the 8–2 hierarchical adder compressor combined with a Brent-Kung adder in the final sum saves on average 29.4 % of total power dissipation, when comparing with SSD implemented using the arithmetic operators automatically selected by the synthesis tool.","PeriodicalId":404022,"journal":{"name":"2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129593179","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}

Wakeup uncertainty and shut-down metastabilities are used as additional entropy source to the timing jitter of the ring oscillators. To be able to change the stability of the rings, multiplexer and inverter are added to each ring. 34 ring oscillators are combined with an XOR gate to generate an irregular waveform that is used as the sampling clock. The select input of the multiplexers are controlled with a control unit. A signal that causes stability change with 2MHz frequency is routed from controller to the select inputs of the multiplexers and the XORed signal is masked with 2MHz, and 10ns width pulses. To reduce the speed of sampling, the irregular signal is downsampled that results in a final throughput of 13kbps. All of the circuits mentioned in this paper is implemented in Xilinx Zynq7000 FPGA. Furthermore, NIST 800–22 test suite is used to test the designed RNGs. Data sets of one million bits are collected with a UART module. All the NIST 800–22 test suite requirements are satisfied with the new proposed RNG.","PeriodicalId":404022,"journal":{"name":"2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131242761","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}
