The measured input and output matching bandwidth are 0–20 GHz where both the input and output return losses are greater than 10 dB. Measured average insertion loss from Tx or Rx port to different output ports are 2.72 dB, 3.6 dB, 4.5 dB and 5.9 dB at 3 GHz, 6 GHz, 10 GHz and 17 GHz, respectively, with a power consumption of less than 1 mW. When the output ports were connected to PCB connectors, 0–18 GHz matching bandwidth was obtained by flip chip mounting, quarter wavelength microstripline impedance matching and optimization of the thickness and dielectric constant of printed circuit board.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"77 1","pages":"706-709"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90648997","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 ambient light could create a DC offset or signal with specific frequency range. Thus, we propose analog filters design in the VLC Analog Front-End (AFE) receiver that can eliminate the ambient light noise. The proposed design uses DC offset removal, incorporated with automatic and manual adjustment mode. In automatic mode, we design the analog filter using High Pass Filter (HPF) which have fc = 10Hz; meanwhile, in manual mode we design a reference circuit using potentiometer and differential amplifier for direct current blocking. For reducing signal interference from lamp flickering, the proposed design uses Band Stop Filter (BSF) which has fc = 100Hz. The experimental results, both simulation and realtime, show that our proposed design can reduce signal interference and ambient light. We also test the design using PWM and BPSK modulation to evaluate Bit Error Rate (BER) performance.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"10 1","pages":"581-584"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86580974","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}

Two experiments were conducted to test the usability and security level of the three password systems. The results suggested that the 3D password system may have the highest security level among the three systems, whereas the pattern lock and PIN systems were likely to be perceived as more usable.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"1 1","pages":"458-460"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82986663","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 develop an execution flow to control the processor shield and run the SBST program without interfering other processes and on-bus devices. Finally, we present a case study that executes the SBST program under Linux kernel on an ARMv5-compatible processor system. Our method can successfully switch the test process and the kernel process and achieve the expected high processor fault coverage. The hardware overhead of the processor shield is 2.6% compared to the logic part of the processor.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"13 5 1","pages":"149-152"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82876060","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}

In order to increase hardware and energy efficiency, a new architecture for fully coherent SOQPSK demodulation is proposed that is suitable for continuous and burst mode transmission. It contains Decision-Directed (DD) synchronization loops for frequency, phase and timing offsets and a low complex method combining robust Start of Frame (SoF) detection with Phase Ambiguity Resolution (PAR) based on nested Barker codes. A coarse grained pipeline structure aims for minimal clock speeds and energy consumption while keeping the overall throughput high. Large complexity reductions are achieved by a multiplier-free Matched Filter (MF) design.

In the cascading process, links can be critical for the propagation of failures. Then It is possible that switching off some links may help the network improve its robustness. In this paper, with the consideration of both the electrical characteristics and complex network structure, we try to assess how the robustness of the IEEE 118 Bus can be improved by switching off a set of transmission links. An evolution algorithm is applied to achieve the optimal performance. Simulation results show that the proposed strategy can effectively relieve the damage to the power system caused by cascading failures at a low cost.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"163 1","pages":"54-56"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80320426","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}
