The influence of various factors on the results of calculation of IV-characteristics of the single-electron semiconductor devices is investigated with the use of the physical model.
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
In this paper, we investigate optimum radiation hardened by design (RHBD) for use against single-event transients (SET) using low-pass filters (LPF) including RHBD techniques against single-event upsets (SEU) for sequential logic in 45 -nm technology in a terrestrial environment. Three types of LPF were investigated regarding their SET pulse immunities, area penalties, and performance penalties. We...
Depropanizer is an energy consuming process, but it is very important in the process of ethylene. For deep analysis and optimization of the operation conditions of depropanizer, an model was found based on strict first principle, than simulation and optimization work was carried to get the best operation conditions. The model was firstly founded by open formed formulas under the consideration of quickness...
Wireless network coding has the potential to enhance the capacity of wireless mesh networks (WMNs). However, most of the work considering the practical deployment of network coding in WMNs considers only IEEE 802.11 based medium access control (MAC) layers. The recent emergence of sophisticated MAC standards supporting WMNs (e.g. IEEE 802.16) make it necessary to view the deployment issues for network...
Advances in micromachining technology can facilitate the integration of SAW (Surface Acoustic Wave) devices and CMOS circuitry on IC scale substrate for Monolithic fabrication. The optimal design and performance of these filters can be reached by using new Smart materials. The key component in the structure of the SAW device is the piezoelectric materials used which depends mainly on some important...
This work reports real-time soft-error rate (SER) testing of semiconductor static memories in both altitude and underground environments to separate the component of the SER induced by the cosmic rays (i.e. primarily by atmospheric neutrons) from that caused by on-chip radioactive impurities (alpha-particle emitters). Two European dedicated sites were used to perform long-term real-time measurements...
Plasma-exposed Si surface related to Si recess in source/drain region was investigated in detail for various superposed bias configurations with frequencies of 13.56 MHz and 400 kHz. Two different bias powers were utilized by an inductively coupled plasma reactor (ICP). The surface layer (SL) and the interfacial layer between the SL and Si substrate (IL) were analyzed by spectroscopic ellipsometry...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
For application researches of the detection for the gas signal source, a method for orientation estimation of the gas signal source in the two-dimensional space and its algorithm are presented in the paper. In the method, a mode of dual-line gas sensor array is applied to sample the signals of the gas concentration in real time, and the time delay estimation, an approach of the signal processing,...
In this paper, the design of a compact planar bandpass filter above a defected ground plane is presented. The filter is designed as a combination of microstrip resonators and exploits the properties of a planar electromagnetic bandgap (EBG) structure patterned unto the ground plane of the printed circuit board material to provide a very wide stopband of up to 5 times the fundamental frequency. The...
