The architecture is digital friendly because it creates a pulse-width modulated (PWM) output instead of a DC voltage; hence, it can be directly interfaced with a digital counter instead of a power-hungry analog-to-digital converter. The proposed design does not use a reference current, which is the prime energy consumer in most temperature sensors, due to required feedback amplifiers. Additionally, reference current devices require large voltage headroom while their resistors occupy large die area. The proposed design expresses the output as a ratio, relative to a reference pulse. Therefore, it is less susceptible to process-voltage-temperature (PVT) variation. The proposed design achieves a temperature accuracy of +0.23°C to-0.22°C within the temperature range-20-80°C, while consuming only 11.2nW at 27°C, while operating from a supply voltage as low as 450 mV.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"59 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":"114201800","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}

Such systems find applications in solving inverse problems, distributed optimizations (convex and combinatorial) and machine learning. In this paper we will discuss our recent work that connects dynamics and algebraic graph theory.

This paper presents a non-linear feedback ring oscillator (NL-FRO) based entropy source for implementing high performance TRNGs on FPGAs. The proposed NLFRO structures harvest randomness from noise and unpredictable variation in delay cells and bi-stable elements which are further amplified by non-linear feedback loops. The outputs of NLFROs show chaotic behavior, making them suitable for implementing high entropy, high speed and attack resistance TRNGs. Three NLFRO-TRNGs are implemented and tested on an Altera 60nm FPGA device. Raw entropy and statistical properties of the NLFRO-TRNGs are examined by the NIST 800-22 entropy estimation and NIST 800-90B statistical test suits.

In our approach, a single-scroll chaotic system is modeled by a fuzzy logic circuit, with the support of physical entropy sources.

The modeling of the chaotic map by fuzzy logic circuits enhance the system immunity to noise and assure a certain degree of parameter deviation robustness. The frequency, operating up to 10 MHz, provides high throughput random sequences, which pass the test of full NIST random number test suite.

This solution has the advantage of relaxing the bandwidth constraints on the feedback path analog to digital converter (ADC) which digitizes the PA distorted output which may spread over several hundreds MHz in the latest generations of mobile communications. However, the subband approach still has some limitations such as signal reconstruction and subband aliasing which limits its implementation on a wide scale. In this paper, an FFT-Based DPD technique that enables to compute the predistorter without interpolating signals is presented. Thanks to the frequency domain approach, the subband signals can be combined easily to compute the fullband predistorter directly. Moreover, the proposed technique offers the possibility of selecting specific frequency bins for the computation. In particular, the subband edges can be ignored which will result in relaxed bandwidth constraints and selectivity for the subband ADCs. Simulations show that the proposed FFT based subband DPD performs as good as the conventional time domain least-square approach even while excluding up to 13% of the FFT bins at the band edges.","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":"127683901","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 method exploits the highly correlated nature of the different sources of interference, being part of the same electrical grid, and their narrow frequency bands. The idea is to use a very narrow pass-band filter around 50 or 60 Hz to get signals with high PLI content before applying a spatial filtering by principal component analysis (PCA). This way, beamforming are done on the frequency bands where PLI are presents. Also, it ensures that even if the PLI has a smaller overall power than the desired signal, it will be easily found as the most powerful component of the decomposition. The PLI can then be removed from the signal. With trivial modification, harmonics of the PLI can also be removed. The approach was used in the context of muscle behavior analyses of low back pain patients using a sEMG array of 64 sensors. The performances of the filter are studied by experimental and semi-empirical methods. Compared to the usual notch filter, an improvement of up 10 dB is found.","PeriodicalId":112526,"journal":{"name":"2018 16th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"6 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":"132975505","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}
