In this paper, we propose a new consensus clustering algorithm, which is based on an existing clustering paradigm, called enhanced splitting merging awareness tactics (E-SMART). The problem of determining the number of clusters, which affects many state-of-theart consensus clustering algorithms, is addressed by the proposed CoCE-SMART algorithm. The idea behind CoCE-SMART is that SMART is used repeatedly...
The interest in the subject of time series analysis started in mid 1920s. The use of real valued prediction filters for predicting and attenuating temporal reverberations present in the recorded seismic signals, known as deconvolution, emerged in mid 1950s. The use of complex valued prediction filters along space axis on constant frequency seismic data for coherent signal prediction and random noise...
The increasing demand for wireless data bandwidth and the rapid adoption of LTE and LTE Advanced standards push radio-frequency (RF) IC designers to develop devices with higher levels of integrated RF functions, meeting more and more stringent specification levels. The substrates on which those devices are manufactured play a major role in achieving that level of performance [1]. In this paper, Soitec...
This paper concerns the underdetermined case of the blind source separation problem, i.e. the situation when the number of observed mixed signals is lower than the number of sources. The general concept that we propose in this case consists of a differential source separation approach, which uses optimization criteria based on differential parameters, so as to make some sources invisible in these...
In this paper the properties of a class of piecewise continuous systems subject to measurement noise are studied especially regarding their possibility to be stabilized around a whatever vector whitin a finite set of desired stabilization points. Such a problem is a typical control issue in many real systems (vehicles attitude control, robotic manipulators, etc.). Conditions under which global asymptotic...
The implementation of FINFET devices in the SRAM cell provides many benefits over that of planar bulk devices. The short channel effect, drive current and mismatch can be better controlled. Several FIN number options among PU(pull up device), PD(pull down device) and PG(pass gate device) can be selected to achieve the good read noise margin and write margin. But in highest-density SRAM cell, in order...
In this work we investigate the impact of the in height of FinFET transistors on the Soft Error Rate and Static Noise Margin of a FinFET-based SRAM cell. 3-D TCAD environment is used for the analysis. Results show that increases the fin height of FinFET transistors degrades the radiation robustness of the SRAM cell. However, increases the fin height of FinFET transistors improves the Static Noise...
In this work, we investigate and explain the time-dependent behavior of shot noise in Silicon quantum dot-based double-tunnel junctions by means of a three-dimensional self-consistent simulation and a Monte-Carlo algorithm following the time evolution of the system. We demonstrate the strong link between autocorrelation functions and electron waiting time distributions, i.e, the time between two consecutive...
We report the fabrication of polycrystalline silicon piezoresistive cantilevers with submicron width and thickness for static force measurements, using electron beam lithography (EBL) and silicon micromachining. For cantilevers with length of 150 µm, leg width of 500 nm and thickness of 320 nm, a force sensitivity of 97 µV/pN and a resolution of 30 pN have been obtained. Bigger cantilevers (leg width...
With the advent of internet, creation and delivery of digital data (images, video and audio files, digital repositories and libraries, web publishing) has grown many fold. Along with it, issues like protection of rights of content and proving ownership arises.
Breakdown voltage, mean gain and excess noise factor of CMOS-compatible p-n junction silicon avalanche photodiodes are predicted using the dead space multiplication theory. Measured dark current and breakdown voltages are also reported supporting low-voltage operation.
Motivated by the practical requirement for delay and complexity constrained broadcasting, we study uncoded transmission of a pair of correlated Gaussian sources over a two-user Gaussian broadcast channel with unit-delay noiseless feedback links (GBCF). Differently from previous works, in the present work we focus on the finite horizon regime. We present two joint source-channel coding schemes, one...
This paper investigates the issues of acoustic feedback in a new kind of application, sound inhibition (SI) system, which is based on the multiple channel active noise control (ANC) technique and implemented by using Filtered-X Least Mean Square (FXLMS) algorithm. The presence of acoustic feedback degrades the performance of SI system, and in the worst case the SI system may be unstable. Here we propose...
We address the problem of controlling bloat in genetic programming(GP) for image noise reduction. One of the most basic nonlinear filters for image noise reduction is the stack filter, and GP is suitable for estimating the min-max function used for a stack filter. However, bloat often occurs when the min-max function is estimated with GP. In order to enhance image noise reduction with GP, we extend...
High-frequency microwave noise performances (2 GHz to 19 GHz) were investigated on AlGaN/AlN/GaN High Electron Mobility Transistors (HEMTs) with 0.15 µm T-gate fabricated on high resistivity 4-inch Silicon. The HEMTs exhibited maximum drain current density (IDmax) of 830 mA/mm, maximum extrinsic transconductance (gmmax) of 353 mS/mm, unity current cut-off frequency (fT) of 65 GHz and maximum oscillation...
III-V Tunnel FETs (TFET) possess unique characteristics such as steep slope switching, high gm/IDS, uni-directional conduction, and low voltage operating capability. These characteristics have the potential to result in energy savings in both digital and analog applications. In this paper, we provide an overview of the power efficient properties of III-V TFETs and designs at the device, circuit and...

A novel method of using complementary split-ring resonators (CSRRs) structure in power/ground plane pair for wideband simultaneous switching noise (SSN) isolation is presented. Compared with traditional mushroom-like electromagnetic band gap (EBG) and coplanar EBG, the proposed nested CSRRs structure only need to be partially etched on the power plane and is easy to be fabricated, while the performance...
Full-Duplex radio provides many benefits beyond improving spectral efficiency. However, canceling the self-interference completely is a big challenge behind Full-Duplex wireless. Although many intelligent efforts devote to active analog radio frequency self-interference cancellation (AARFSIC), the power of the residual self-interference (SI) after the AARFSIC is still much stronger than that of the...
