The proposed filter aims to enable IEEE 802.11 b/g and UWB standard coexistence in the same terminal device. The filter topology is composed of two paths: the first path contains an all-pass function while the second path contains a band-pass one. By this way, the signal is divided at the circuit input and is combined at its output forming a notch response that exhibits a high rejection at the center frequency of the band-pass filter function. Experimental prototype implemented on Rogers4003 multilayer substrate is built in order to show the benefit of this concept design.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114585669","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 circuit under test is used in active capacitance multipliers, V-I scalar circuits, Biquadratic filters and many other applications. This circuit is often used to implement voltage followers, current followers and voltage to current converters. Five faults are assumed per transistor. It is shown that, to obtain 100% fault coverage, the CCII has to be operated in voltage to current converter mode. Only two test values are required to obtain this fault coverage.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114842871","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 circuit involves a Low Noise Amplifier (LNA) combined with the SRO, for the purpose of current reuse, operating in 402-405 MHz MICS band. Demodulation is done utilizing the phase content of the signal that has been regenerated by the front-end of the receiver (LNA & SRO). The demodulation is achieved without downconverting incoming RF signal into IF band which eliminates the use of a Local Oscillator (LO), a Phase Locked Loop (PLL) or an Analog-to-Digital Converter (ADC). The complete design of the receiver made use of 0.12 μm CMOS technology and pre-layout simulations confirm proper and efficient demodulation of 8-PSK signals. The power consumption of around 175 μW is measured for an input of -80 dBm at a rate of 4Mbps.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115794513","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 this paper, high performance fixed coefficient FIR filters are designed by exploiting the advantages of 6-input LUT structures. Using the proposed methodology, fixed coefficient multiplication and accumulation is employed as only two cascades of 6-input LUTs in the critical path. Therefore high performance FIR filtering is possible without any pipelining in the system. For the multiply-accumulate operations only (6, 3) counters are employed together with redundant carry double save operations. 440 MHz clock frequency is reached for the designed 25 tap FIR filter on the Stratix II family FPGA. The proposed arithmetic structure provides more than 90% speed advantage over hardware multiplier based multiply accumulate operations.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125041488","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}

This technique enables sensitization of EM related faults. First, a channel-connected graph is built from a mixed signal transistor circuit, then the current activation condition is formulated as satisfiability constraints annotated in the channel-connected graph. This results in a weighted constraint satisfaction(WCS) formulation.

The Gaussian filter is a convolution operator which is used to blur images and to remove noise, whose convolution implementation can be designed in hardware using only shifts and addition operations. In this work we evaluate the levels of approximations in computing or loss of accuracy in the arithmetic dataflow that the Gaussian filter can tolerate for a set of eight images. Our work deals with different levels of approximation in Ripple Carry Adders (RCA) which are part of the Gaussian filters adder tree implemented in hardware, and later compared to the best precise implementation of the same filter. Our results show an average energy savings of up to 40% and 25% for the approximate 3×3 and 5×5 Gaussian filters, respectively, without compromising the overall filtered images quality.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127203564","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}

This technology has several advantages: (1) communication is controlled and secured in the space, as light does not go through walls, (2) unlike radio waves, visible light does not interact with the electronic components which makes this communication technology suitable for electromagnetic wave-sensitive environments, and (3) visible light offers wider bandwidth and communication can have reach very high rates (i.e. gigabit). In this paper, we investigate power consumption issues for VLC systems in combination with power transreceiver technologies. We propose a Signal Conditioning Unit in solar panel-based VLC receiver to regular the input signal which was deformed from output of solar panel. A solar panel acts as photo-detector and also powers the receiver circuit by converting the light signal into electronic signal. The frequency response of our solar panel is 50 kHz after conditioning.
