The conventional metal connections cease to meet the growing demands of the quality of information transmission, speed and noise immunity. This is especially acute in the inter-core connections of ultra-large scale integrated circuits. One of the pro...
Recently the films of solid solutions CuZnSn(S Se) (CZTSSe) are used as the light absorbing layers in the thin film solar elements. The CZTSSe films are the Cu(In, Ga)Se analog, but do not contain rare and expensive In and Ga elements. In this study...
At present the heteroepitaxial structures based on gallium arsenide and its solid solutions are the basis for manufacturing of solid state electronics devices. The main method of growing heteroepitaxial structures is the chemical deposition from vapo...
The up-to-date systems of space communications, navigation, etc require the development of the electronic component base. The application of the reliability increase methods results in degradation of the efficiency, power consumption and area. The he...
The high voltage silicon transistors and diodes are used in the direct current sources, in the circuits for conversion of alternating current to direct current, in accumulative batteries as separate devices and in the circuits «bridge», «half-bridge»...
The frequency micromechanical accelerometer (MMA) measures the acceleration, based on a change of the resonator frequency, when the acceleration is caused by the displacement of the inertial mass. Its sensitivity can be influenced by such factors as ...
A design and size of the membrane module package have a significant impact on its characteristics. It is necessary to use the finite element modeling calculation of the frequency response of the membrane module membrane due to complexity of the packa...
In modern satellite communication systems, the side repeaters, using an active phased array antenna receiving and transmitting modules, include, as a rule, the discrete phase shifters. The latter are designed in the form of the hybrid integral circui...
The adder represents a logic operation unit, executing an arithmetic adding of two binary numbers in the arithmetic-logic devices being a part of the processors. Two types of the adders: single-bit and multibit ones have been distinguished. Depending...
The printing time and accuracy are the main problems of a 3D printer. To obtain the high accuracy of the position of the motor shaft and to solve the problem of the missing step, it is necessary to use a DC motor instead of a stepper motor. In this s...
Nowadays, the task of increasing the efficiency of the information retrieval is of particular importance because of the implementation semantic Web concept. In this study a model for estimating the information retrieval efficiency based on the freque...
