The advantage of this type of device is the electronic formation of antenna array beams without the need for mechanical action on the system elements. Such electronically controlled circuits are developed using a computer study of antenna elements and corresponding electronic components in the frequency or time domain. In our case, the simplest 4x4 Butler matrix was miniaturized using inductive and capacitive elements combined into artificial transmission lines and installed instead of segments. Such actions allowed to reduce the area of the matrix by 70.16%.","PeriodicalId":218866,"journal":{"name":"2022 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126438376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The functional scheme of the two-channel discriminator with the detuned channels according to some parameter is given. The operation of the named discriminator is described. It is noted that the measured parameter is a random function of time. The occurrence of dynamic error is shown, as well as the appearance of fluctuation errors under the influence of noises. The assumption system accepted in the paper allows considering the servo-measuring device as a linear system according to the measured parameter. The analysis is done for a quadratic envelope detector. It is noted that the effective bandwidth of the tracking meter depends on the level of noises. Expressions for definition of a dispersion of errors of measurement both in the presence only additive hindrances, and at action on a signal multiplicative hindrance are received. The coefficients making it possible to estimate the influence of multiplicative noises on deterioration of accuracy of the tracking meter characteristics are introduced. It is shown that these coefficients can be calculated by using the slope of the discrimination characteristic, the spectral density of fluctuations at the discriminator output under the zero error and the coefficients defining the normalizing effect of automatic gain control in the presence and absence of noises.","PeriodicalId":218866,"journal":{"name":"2022 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121416746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously, we proposed a new “improved” smoothing function that ensures a monotonic increase in output resistance from the minimum value at the beginning of the triode regime to the maximum value at saturation. We used this smoothing function for compact modeling of an “ intrinsic” (with neglecting the contacts parasitic resistances) MOSFET. Later, we proposed a linear approximation for the drain current dependence on drain bias in the saturation regime for the “extrinsic” (taking into account contact parasitic resistances) MOSFET without taking into account body effect. This approximation is based on the proposed by us equations for the output resistance of the “extrinsic” MOSFET in the saturation regime (one for Level l and second for BSIM3 /4 models). Later, we generalized this equation on the case with accounting for the body effect, that was considered in the linear approximation. Note that modern transistors with steep retrograde body doping profiles exhibit approximately linear relationship between a threshold voltage and a source-to-body bias. In addition, we have shown how it is possible to convert a transistor with a body terminal to an equivalent transistor without a body terminal. In this paper, we use an “improved” smoothing function for compact modeling of the drain current of an “extrinsic” MOSFET operating in the above threshold regime that accounts for the body effect in the linear approximation. The resulting model yields a monotonic decrease in output conductance, which is important for improving the accuracy of MOSFET compact modeling in CAD software. Furthermore, we analyze in detail the relationship between the equation obtained for the output resistance of the “extrinsic” MOSFET in the saturation regime with the output resistance of a common-source amplifier with source degeneration. Note that in the theory of a common-source amplifier the circuit that consists of an NMOS transistor with a resistor in series with its source terminal is known as a transistor with source degeneration.","PeriodicalId":218866,"journal":{"name":"2022 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122928841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spacecraft dielectrics should have increased conductivity to exclude physical possibility of electrostatic discharges in them when exposed to near-Earth plasma electron radiation. It is possible to achieve an increase in the conductivity of dielectrics by introducing a finely-divided conductive compound into them; its concentration should be carefully controlled in order to remain near the percolation threshold. However, during preliminary research, it has been found out that application of voltage to metal-dielectric-conductor structures (MDM), manufactured on the basis of such dielectrics, may lead to spontaneous instabilities of the electric current passing through the dielectric. A method for testing nano-conductive dielectrics of this type for long-term current flow has been developed. The purpose of this paper is to explain the mechanism of a significant decrease (up to 10 or more times) in the conductivity of dielectrics with increased conductivity during the flow of high currents and to develop a physical model on this basis that would allow to explain the observed phenomenon. Such a model will make it possible to predict the life time of dielectrics, working not only in near-Earth plasma, but also during interplanetary missions (for example, to Jupiter, where the flows of charged particles are three orders of magnitude higher than the near-Earth ones).","PeriodicalId":218866,"journal":{"name":"2022 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133874939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subject of the research is the methods of Volterra filters effective realization, based on representation thereof in matrix form and decomposition procedure. The article is aimed at development of ways of effective realization of two-dimensional (2-D) discrete Volterra filters due to paralleling and unification of computing operations. To describe the process of multidimensional discrete filtering the matrix representation of the Volterra filters is used. The concept of block convolution is introduced, which makes it possible to reduce the calculation of nonlinear convolutions to a sequence of calculations of linear 2-D convolutions, and then to estimate the volume of necessary calculations. An approach to realization of 2-D discrete Volterra filters is proposed, based on decomposition of matrix representation on non-linear 2-D convolutions. The given approach allows reducing the problem of nonlinear Volterra filters realization to series-parallel execution of linear 2-D convolutions and may serve as a foundation for development of parallel computational structures intended for realization of high-speed algorithms of non-linear filtering. The method of realization of 2-D discrete Volterra filters, based on execution of decomposition of the matrix representation of non-linear convolutions, allows to use the known methods and algorithms of multidimensional filtration for realization of Volterra filters and to give clear interpretation thereof. The suggested method of Volterra filters realization through using series-parallel execution of calculations provides an opportunity of realization thereof based on systolic processors.","PeriodicalId":218866,"journal":{"name":"2022 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128984600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
