Introducing a polynomial of squared frequency in the numerator of squared modulus of the Butterworth filter requires that a similar polynomial is added to the denominator of this squared modulus function if one wants to preserve the flatness property. After these two modifications are made the restoration of transfer function gives a transitional filter. If the polynomial introduced in the numerator includes all zeros of inverse Chebyshev filter then the restored filter will be the inverse Chebyshev filter. In case of partially restored flatness one obtain a transitional filter. An example of transitional filter for the fifth order Butterworth and inverse Chebyshev filters is calculated.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123569064","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 particular, we study deterministic vs. stochastic dynamics by distinguishing chaotic behavior from noise. The proposed approach is general enough to detect any type of noise with no restriction on the noise distribution. It is based on a statistical proof by contradiction using hypothesis testing with Lempel-Ziv Complexity (LZC) method as discriminating statistics. The LZC method is adopted as a nonparametric test that has the advantage of detecting any kind of noise. Experimental results on a $Sigma-triangle$ Modulator and a Lorentz circuit showed that the proposed approach provides a reliable distinction between chaotic/hyperchaotic behavior and non-Gaussian noise.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129631136","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}

Its reconfigurable design provides versatility to comply with various applicative conditions. The proposed design is based on MASMOS transistor providing up to 32.7 dBm of saturated output power (PSAT) in LTE-band VII, while allowing a good tradeoff between linearity and power consumption. An analysis of the output combining transformer dimensioning is presented to optimize performances. Small signal and large signal post-layout results are reported for three operating modes: high performance (mode 1), low consumption (mode 2) and high linearity (mode 3). In its high linearity mode, providing the best tradeoff between output power and quiescent consumption, the PA achieves 31.6 dBm of 1-dB compression point (P1dB), at only 0.9 dB back-off from the PSAT. The PA is presently in fabrication. It is believed by the authors to be used in applications requiring high performance and adaptability to varying conditions, especially for the internet of things (IoT).","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133361787","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}

Capillary microfluidics overcome the limitations of ‘lab-around-a-chip’ by permitting a pre-programmed liquid delivery and flow control to be embedded in the chip without the need for complex peripheral equipment. In this presentation, we chart the progress of microchannel-based capillary microfluidics, from the early stages of the cleanroom environment to the state-of-the-art in rapid prototyping. Following recent progress, we have introduced a new terminology – capillaric circuit (CC) – that both reflects the advances and provides a clear and distinct vocabulary that overcomes the ambiguity due to the multiple usage of the word “capillary”. We briefly describe the governing parameters of self-filling microchannel-based microfluidics CC, and, by analogy with electronic circuits, the deconstruction of CCs into basic fluidic elements and components. The library of basic capillaric elements is expanding. 3D printing enables rapid production of fully functional CCs, establishing CCs as a powerful increasingly complex microfluidic technology that can serve diverse applications.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133108744","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 further show in frequency domain that data-transition DFE boosts the high-frequency components of data without attenuating their low-frequency components. Moreover, data-transition DFE exhibits a first-order error-shaping characteristic that maximizes vertical eye-opening. A new loop-unrolling scheme specifically tailored for data-transition DFE is presented.

These features can be encoded using a binary (1' or '0') encoding technique. The encoded feature value of '1' provides more information about the feature than '0' does. In view of this, we first propose a fusion in order to fuse encoded features obtained from individual feature encoders for a multimodal biometric system, and refer to it as the first-stage fusion (FSF). Next, another fusion is carried out between the unimodal system which provides the best performance in that multimodal system and the proposed FSF, and referred to as the second-stage fusion (SSF). Genuine acceptance rates @4.3% and @4.4% false acceptance rates, and equal error rate are utilized for evaluating the performance of a multi-biometric system using the proposed fusions. Results show that a superior performance is provided by a multi-biometric system using the proposed fusion scheme in comparison with the performance provided by the system using existing fusions or by the unimodal systems.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131356492","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, however, makes image searching a highly desired operation in many applications. Most of the content-based image retrieval (CBIR) methods usually adopt machine-learning techniques that take the image content into account. These methods are effective, but they are generally too complex and resource demanding. We propose a framework based on image hashing and random forest, which is fast and offers high performance. The proposed framework consists of a multi-key image hashing technique based on discrete cosine transform (DCT) and discrete wavelet transform (DWT) and random forest based on normalized B+ Tree (NB+ Tree), which reduces the high-dimensional input vectors to one-dimension, which in turn improves the time complexity significantly. We analyze our method empirically and show that it outperforms competitive methods in terms of both accuracy and speed. In addition, the proposed scheme maintains a fast scaling with increasing size of the data sets while preserving high accuracy.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134282331","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 sensor node has two coils inside, which are used as an antenna in WPS mode and wireless communication mode. In distance sensing mode, on the other hand, the two coils are used as electrodes to radiate an electric field to neighboring nodes. For switching functions, a normallyon junction type FET (JFET) is introduced so that the node automatically enters into the WPS mode when no energy is left in the node. We evaluated the functionalities and performance of each mode with a prototype. Experimental results show that, in the WPS mode, the two coils are automatically connected to each other, and the node can receive power even if there is no energy left in the node. In the wireless communication mode, 1 kbps communication is possible at a distance of 10 cm. Also, the distance can be measured at a range of 30 mm or less by using two coils as electrodes.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133251911","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}
