The dynamics of the input-less circuit is first investigated by characterizing the attractors lying on the infinitely many invariant manifolds of the circuit state space. Then, both the problems of steering within a prescribed time interval the dynamics from one manifold to another (i.e., switching among different attractors), and of modifying the dynamics onto each invariant manifold are solved via suitably designing the control sources. Some numerical examples are presented for illustration purposes.","PeriodicalId":336302,"journal":{"name":"2020 European Conference on Circuit Theory and Design (ECCTD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129960395","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}

These attacks are majorly employed to understand the camouflaged logic during reverse engineering. The state- of-the-art techniques like scan chain scrambling hinder accessibility of scan chains, but are prone to layout level reverse engineering attacks. In the proposed methodology, the scan design is secured by adding an extra scan input port (DSI) to the flipflop using dummy contacts, which ensure that DSI cannot be distinguished from SI port even with layout based reverse engineering techniques. Dummy scan chain connections are introduced in the design by connecting DSI port to the nearby flipflop Q output port. Our proposed method can withstand Reset-and-scan attack, Incremental SAT-based attack and the recent ScanSAT attack. The performance of this concept is measured in terms of frequency and total power consumption on IWLS-2005 benchmark circuits having up to 1380 flipflops with 40nm technology library. The delay is effected by a maximum of 2.2% with 50% obfuscation without any impact on power, pattern generation time and scan test time.","PeriodicalId":336302,"journal":{"name":"2020 European Conference on Circuit Theory and Design (ECCTD)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121072921","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}

Since biological signals are very low frequency signals, a chopper amplifier which has low 1/f noise is used. Furthermore, the amplifier has a highpass characteristic in order to remove the DC voltage contained in the signals obtained from the sensor. A method to remove the DC voltage accurately and quickly using DC voltage holding capacitors and voltage buffers is proposed. HSPICE simulation results show that the proposed 4-input circuit reduces the chip area by 26% and the power consumption by 29% compared to the conventional circuit.","PeriodicalId":336302,"journal":{"name":"2020 European Conference on Circuit Theory and Design (ECCTD)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131200458","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}

Later on, CNN have been designed using the processing and memory capabilities of memristors. On the other hand, Stochastic Computing (SC) has been proposed as a way to reduce the number of processing elements in a circuits. In this work, we propose using SC to implement a CNN. Specifically, we choose a memristor-based CNN, where all the operations are done using SC. As an example of application, we have used Matlab to create a CNN that performs edge detection on 512x512 grey-scale images. Results show excellent capability, while at the same time the low number of needed elements will allow to implement it in a low cost FPGA-based system.","PeriodicalId":336302,"journal":{"name":"2020 European Conference on Circuit Theory and Design (ECCTD)","volume":"71 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132241331","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 design is based on a specially determined frequency mapping, applied to an digital prototype filter. This analytical design approach yields the transfer function of the desired 2D filter in a factored, closed form. Some efficient, accurate approximations are used, like Chebyshev-Padé method, without resorting to global optimization algorithms. The filter matrices are a convolution of smaller size matrices, an obvious advantage in implementation. Moreover, the obtained filter is tunable, since its coefficients depend on the specified orientation and bandwidth. As proven by given design examples, these 2D filters have a precise shape, with negligible distortions even near the margins of frequency plane, good selectivity and low order.","PeriodicalId":336302,"journal":{"name":"2020 European Conference on Circuit Theory and Design (ECCTD)","volume":"15 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113960265","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}

For the evaluation, we use three different metrics that have already been employed in the relevant literature for measuring the spatial correlation of other PUF responses. Our results prove that the examined PUF responses exhibit little, if any, spatial auto-correlation. Thus, these PUFs can be considered as security mechanisms of high entropy, which can be utilised to enhance the security of the Internet of Things (IoT).","PeriodicalId":336302,"journal":{"name":"2020 European Conference on Circuit Theory and Design (ECCTD)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132593494","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}
