Investigation of impedance analysis and modeling methods in integrated circuits on multilayer printed circuit boards

Abstract

The scientific article is devoted to the main research methods of integrated circuits for the influence of impedance characteristics on the confidentiality of transmitted information. Computer modeling of mathematical and physical models of integrated circuits using simulation software located on printed circuit boards is presented in the aspect of noise analysis that occurs during the transmission of information between receivers and transmitters located inside integrated circuits. The key factors influencing the level of interference, including electromagnetic and electrostatic interactions, as well as their impact on the integrity of transmitted data, are considered. An overview of the technical characteristics of hardware protection methods is given, with an emphasis on physical methods to ensure the confidentiality of processed information. Special attention is paid to the principles of implementing protective mechanisms at the hardware level, aimed at reducing the influence of external electromagnetic influences and electrostatic discharges. The main methods of noise reduction, including shielding, filtering and optimization of the topology of printed circuit boards, ensuring the reduction of electromagnetic radiation and interference, are considered. The design features of integrated circuits that help minimize vulnerabilities associated with unauthorized access to transmitted data are analyzed. The results obtained can be used in the design of integrated circuits and digital systems requiring increased resistance to external interference, as well as in the development of new methods of hardware protection of information in conditions of high-speed data transmission.
