It exploits the process variation of a single transistor as the load of the current mirror to generate a reliable digital signature for the chip. By employing a cascode NMOS transistor in the current-mode PUF architecture, the proposed PUF greatly boosts the output impedance. As a result, the tiny mismatch current can be amplified to a large output voltage swing. In addition, the area overhead per bit is only two minimum-sized NMOS transistors: one for the load of the current mirror, the other one for the selecting switch. Moreover, the proposed PUF design is validated by our extensive post-layout simulation using UMC 65nm CMOS technology, with a power consumption per bit as low as 0.13μW. The average area for each response bit extracted from the design layout is 5.47μm2.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81358811","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 main objective of this algorithm is to use an alternative error correction scheme which is called as the Hamming code, replacing the conventional CRC code. Moreover, to possibly increase the CAN's frame rate of the system. The bit's positions of the redundant bits ‘r’ and the bit streams of the frames from the start-of-frame (SOF) to the control bit frames are determine. These bits will be fed into the redundant bit controller to compute for the necessary r. The redundant bit's positions are in power of 2, and will be calculated using modulo-2 operation. This proposed method is synthesized using Xilinx Virtex-5 FPGA. The simulation results shows a significant increase of CAN's frame rate and, it minimizes the bits stuffing payload and can be a better option for detecting and correcting error in CAN System.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76966036","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}

We consider a generic type of networks consisting of two kinds of nodes: hosts and routers. In this kind of network, the traffic performance is closely related to the traffic generation pattern which is determined by the hosts' locations. We evaluate the performance of six kinds of methods to locate the hosts in Erdos-Renyi (ER) random network, Barabasi-Albert (BA) scale-free network and the Internet AS-level network. Our simulation results show that the traffic generation pattern has a significant effect on the traffic performance and provide insights into network design.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75741515","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}

A low (de)modulation frequency is used for long range estimation, which saturates the photodiode due to integration of high-intensity background light. Therefore, long range cameras are generally limited to indoor applications. In this work, a circuit is proposed to subtract up to 120 klx BGL for 1.07–9.65 m distance. A (de)modulation frequency of 2.33 MHz with 33 % duty-cycle is used. The measurement results show a range resolution of 1.49 cm and 65 cm for 1.07 m and 9.65 m distance, respectively at 120 klx background light. The circuit is fabricated and characterized in UMC 180 nm technology.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83938752","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}

While an increase in computational speed over the conventional method of solving a system of nonlinear ordinary differential equations (ODEs) has been confirmed for a single ganglion cell, the notion is extended to a retinal dual-pathway simulation which provides for a significantly improved adoption for organic mechanisms. There are various numerical methods in solving such a system which all have a bearing on both speed and error, and as such, systematic analyses using two common forms of integral solving methods are shown to improve the overall performance of simulating the extended pathway of the retinal model.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82390570","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}
