In RF wireless communication systems, oscillator plays the role of providing signals, therefore high stability and low phase noise oscillator is very important. This paper use the negative resistance theory of FET, let the circuit is in an unstable state. And the use of dielectric resonator (DR) as a signal source, design of the dielectric resonator oscillator (DRO) operating frequency is 10.5GHz...
We report on a vision sensor architecture relying on a pixel-embedded memristive device to perform dynamic background subtraction as basic image processing components, aimed at detecting anomalous events in the scene. A Light-To-Frequency Converter generates digital pulses, which are linearly proportional with the light intensity. During the exposure time, a certain number of pulses, with proper width...
This paper presents the simulation of different types of single as well as composite power quality events (PQ) for analysis and characterization. Most of the power quality problems (the transient and steady state disturbances), which can occur in the distribution system, have been obtained. Six single PQ event such as voltage sag, voltage swell, interruption, transients, voltage notch and harmonics...
In this paper, an X-tree clock distribution typology has been applied, a two stage, 7.5 mm ∗ 7.5 mm dimension standing wave resonant clock distribution network can perfectly convey clock signals everywhere on to the chip without taking up much of the chip area (around 1.28mm2, which is 2.2% of the total chip area), and dissipating 51.75 mW power. The clock jitter is 1.86ps and almost zero clock skew.
In this paper, we present the implications that the Lightly Doped Drain-LDD technique used for Metal Oxide Semiconductor-MOS fabrication of n-channel transistor has on different device parameters. The discussion focuses on the influence of the n- doping of drain, respectively source on the electric field, one of the most important issues of today's technology, but takes also into consideration another...
In this paper, analyses on the design of the underwater track vehicle (UTV) with ladder trencher for cutting underwater soils are conducted.

Tractive thrust and normal reaction are analyzed and used to assess the traction, weight...
In this paper, an overall comparison between the Quadratic Boost Converter (QBC) & Cascaded Converter or Cascaded Boost Converter (CBC) is given in terms of ideal condition, as well as with the consideration of Equivalent Series Resistance (ESR) of inductor-capacitor. The differences in the voltage gain due to the individual effect of inductive and capacitive ESR is shown in this paper. The parameters...
The aim of this paper is to present a new method of three-dimensional stratification of the soil, as well as to describe an apparatus which can be used to automatically measure its electrical conductivity. This apparatus uses Wenner array which, along with an optimization procedure, enables an easy three-dimensional stratification of the soil in large areas. The 3-D stratification is obtained from...
This paper proposes a new approach to achieve on-line identification of the q-axis inductance and the resistance of the interior permanent magnet synchronous motor (IPMSM) on the basis of the relationship between the mismatch of Lq and the d-axis feedback current. The value of the d-axis feedback current depends on the mismatch of Lq, and the consecutive samplings of the d-axis feedback current make...
An atomistic Monte-Carlo simulator of TaOX-based resistive random access memory (RRAM) with bi-layered Ta2O5−X/TaO2−X stack is developed by considering generation/recombination (G-R) of oxygen vacancies (VO) with oxygen ions (O2−), phase transition (P-T) between Ta2O5 and TaO2 as well as interactions of Ta2O5−X/TaO2−X stack. The stack induced effects involving changeable Schottky barrier (SB) at the...
Commonly known analytical prediction methods for winding loss in switched reluctance machines provide comparatively inaccurate results but are very fast. Finite element analyses, however, yield rather exact results but at high computational cost. This paper introduces harmonic superposition as a third approach that promises sufficiently accurate loss estimations at low computational cost. At that...
Currently, it's lack of repair mechanisms for forming diagnosis in the industry. Normally, once the card goes wrong, it will be replaced with the entire board, that is wasteful. Based on the advantages and disadvantages of various diagnostic methods, a fault diagnosis method is presented in this paper which is fit for the navigation control card. Taking the LNE001CT navigation control card as an example...
As the modern city arterial traffic, urban rail transit system has good effectiveness. It has regular starts and stops due to its specific operating conditions. A considerable amount of energy has been saved because kinetic energy can be recycled during braking and released when accelerating. This paper discussed the possibility of equipping the rail transit system with the hydraulic storage transmission...
In this paper simulation on the effects of low energy electron radiation and high temperature on the current-voltage (I-V) characteristics of Ni/4H-SiC Schottky diode were investigated. I-V characteristics of the Ni/4H-SiC Schottky diode were simulated based on thermionic emission theory using Silvaco Atlas Technology-computer-aided-design (TCAD) simulation tool. It was found the decrease in the forward...
This paper provides analysis result about effects of parameter variation on mono inverter dual parallel (MIDP) surface mounted permanent magnet synchronous machine (SPMSM) drive system. Parameter variation is natural phenomenon in real system and is caused by manufacturing tolerance, temperature variation, and magnetic saturation. In the MIDP motor drive system, parameter error can be occurs not only...
In our case, the chips passed the Memory of Built-in Self Test (MBIST) test under low voltage, but failed the MBIST test under higher voltage. Shmoo plots illustrate the MBIST failure is soft failure and claim the narrower window than the passed chips at high voltage side. Nanoprobing exhibits NMOS contact (CT) high resistance. Physical Failure Analysis (PFA) shows partial missing of salicide happens...
The process of simulation and implementation of the high-accuracy device by using standard CMOS technology is considered in the paper. The selection of the process flow and changes of the standard circuit design are described. Simulation results and measurements of created devices are presented.
The mechatronic system with variable parameters operating under varying conditions discussed in this paper refers to an electric drive system for winding a strip with constant linear velocity on a drum. The continuously variation of the plant inputs, namely reference and load disturbance, is determined by the increasing radius and hence moment of inertia of the drum. This paper suggests a conventional...
Simulation is expected to become an indispensable educational and research tool for memristive circuits and architectures.

It permits the exploration of the crossbar-based memristive...
In a co-operation between the Institute of Automatic Control at the Aachen University of Technology and the Dräger Medizintechnik GmbH, Lübeck, a well-known developer and manufacturer of respiration devices, a digital feedback control strategy for the pressure-based ventilation was developed. However, the achieved controller is not robust enough against parameter variations (e.g. different patients)...
