The standard DC and RF and characteristics were measured for the 28 nm p- and n- type MOSFETs. The charge based compact model EKV3 parameters were extracted and verified against measured data. Noise parameters for both n- and p-MOSFETs were measured and analyzed in terms of gate induced noise correlation with the drain current noise, short channel effects related noise. The PRC noise model as well...
In this talk, we are briefly surveying our recent results [1] challenging the claim that the memristor is the “Missing circuit element” [2]. The crucial question is if the memristor equations guarantee that the device can be realized by passive components. With active components and feedback, arbitrary device characteristics can be realized. Recent work of Chua indicates [3] that certain type of memristor...
This work proposes an experimental demonstration of the stochastic resonance, a phenomenon widely observed in biology using a 65 nm CMOS artificial neuron. The stochastic resonance has been revealed through two different statistical studies. Moreover, when optimal, a signal to noise ratio at the output of the artificial neuron of 22.4 dB is achieved, for an ultra low power consumption, lower than...
Correlating noise figure measurements between R&D teams and manufacturing teams is becoming both more difficult and more important as LNAs are increasingly integrated with other components such as switches, filters and power amplifiers, to form a Front-End-Modules (FEM) used in wireless devices, thus the test systems must accommodate more complicated test scenarios than a simple LNA requires....
In this talk, we are briefly surveying our recent results [1–3] about two very popular yet often misunderstood concepts in physical informatics: (i) The existence of Johnson noise at near to absolute zero temperature has been debated many times yet it is generally accepted [1]. We point out the fundamental problems [2] with the particular approach the related quantum theories [4] of Fluctuation-Dissipation...
We give a classification of the different types of noise in a quantum dot, for variable temperature, voltage and frequency. It allows us first to show which kind of information can be extracted from the electrical noise, such as the ac-conductance or the Fano factor. And next, to classify the mixed electrical-heat noise, and to identify in which regimes information on the Seebeck coefficient, on the...
Solar energy is one of the most popular renewable energy sources. The control process of the photovoltaic system is usually based on the estimation of grid signal parameters. This paper presents an estimation method based on the FFT procedure, I class Rife-Vincent time windows and the 3-point spectrum interpolation. The accuracy in a real time system depends on several parameters: number of samples...
In addition to the need for security, everyday information exchange must be able to cope with noise and interference. We discuss the noise robustness of a recently-introduced communications protocol inspired by the human cardiorespiratory interaction, based on analysis methods originally developed for reconstructing coupling functions between oscillatory processes underlying the biological signals...
The Kirchhoff-Law-Johnson-Noise (KLJN) key exchange protocol had been introduced as an ultra-low cost alternative of quantum cryptography. Two years ago we have developed a generalized version of the KLJN key exchanger (VGM-KLJN), and we have proved that the system works perfectly secure under much more general conditions that allows compensation of many kinds of imperfections. In this work we focus...
GaN HEMTs are known to outperform GaAs technologies in power applications, while their noise performance drew much less attention. Only recently, results were published for GaN that are competitive in terms of low-noise performance. This paper discusses the optimization of GaN HEMT technology concerning low-noise performance empirically, based on own measurements and on data from the literature. Finally,...
Graphene material exhibits a number of outstanding electronic and mechanical properties that make it very attractive for micro and nanoelectronic applications. Considering graphene field effect transistors (GFETs), considerable efforts were made during the recent years, and the devices at state of the art show impressive high frequency cut-off frequencies. The interest of GFET is particularly strong...
Most of the feedpumps used in industrial systems are not continuously monitored resulting in repair, replacement, shutdown of plant in worst case. In order to increase the safety and reliability of the pump, we will design a monitoring system which measures various parameters and indicate locally and transmits those parameters into internet. The rotating machine to be monitored continually for any...
The adaptive elastic net has been widely studied in the microarray classification due to the elegant performances in gene selection. However, the classification accuracy will be affected if the noise is included. As such, this paper proposes a weighted adaptive elastic net for the binary microarray classification with noise by using the distances from the sample points to both class centers. Furthermore,...
The sensitivity of a recently proposed spike detector exploiting the volatile properties of memristive device is optimised. A 200 nm × 200 nm TiOx memristive device in volatile region is biased with sub-threshold, unipolar and bipolar neural events. The input neural signal is pre-processed using different amplification settings. The resistive state response of the test device in response to the input...
Feedback improves the linearity of the main path; however, this increases the linearity requirement of the feedback path in conventional transmitter Cartesian feedback architecture. To alleviate this issue, the feedback signal should be largely attenuated, which then inevitably degrades the system noise performance. To mitigate the trade-off between noise and linearity, we have invented a new architecture,...
The application of the proposed mathematical tools, that can be used for signal processing self-generating transducers of physical quantities, are considered. Its operating mechanism is based on frequency modulation, when the frequency deviation depends on the intensity of exposure measurement parameter. It is shown that the action for leveling additive errors in the channel the signal generator is...
In this paper, rotor slits on the rotor's outer circumference is adopted to reduce certain harmonic components of radial forces and, hence, acoustic noise and vibration in an interior permanent magnet synchronous machine (IPMSM). The 48th order of harmonic component for the radial force is found to be responsible for the noise and vibration problem in the studied motor. For this purpose, the influential...
This paper addresses the issue of mitigating the noise emission of high-speed permanent-magnet (HSPM) machines. HSPM machines are increasingly used in a large field of applications for their power density and compactness. However, increasing the speed tends to intensify the noise emissions where more and more applications require a quiet operation. The focus of this paper is to propose a HSPM structure...
The paper presents a system that allows the passive reduction of noise and vibration of a three-phase induction machine with a stator damper winding connected to capacitors. This is a simple and effective system for reducing the flux density harmonics of a machine. The theoretical study is based on the equivalent circuit of a machine equipped with the damper winding and the modeling is based on the...
According to the theory of structural sound radiation, the calculation of surface sound radiation is derived for a finite plate. After the vibration level and the sound power level of the dry transformer are measured, the sound radiation ratio of the dry transformer is computed through the experimental method. The estimation for the noise of the dry transformer through the measurement of the surface...
