Summary of the subject: The program of the educational discipline "Fundamentals of microcircuit engineering" is designed for students of the Institute of Telecommunications, Radio Electronics and Electronic Engineering who study in the specialty "Avionics". As a result of successful study of the course program, the student will learn the theoretical principles of circuit engineering and practical skills in circuit design, model and experimental research of avionics units.
The course has a practical orientation, providing students with opportunities to gain experience in circuit design and research of avionics devices. Self-education is considered an integral part of this educational course, and special attention in the program is paid to independent work of students.
The course covers: requirements for parameters and the process of developing avionics; schematic analysis and synthesis; schematic modeling; SPICE models; basic circuits and their modes of operation - operational amplifiers, transimpedance converters, reference voltage sources, stabilizers, multiplexers; pulse generators; analog-digital and digital-analog converters; interfaces; memory devices; programmable logic matrices and devices; avionics signal converters.
The content of the course is aimed at forming students' understanding of the general trend of the development of avionics circuitry, the ability of students to effectively use the acquired knowledge during practical classes in classrooms and when performing laboratory and independent tasks, the ability to find the necessary information in specialized literature and the Internet.
The study of the educational discipline involves the use of MicroCap11 schematic and technical modeling software (evaluation student version) and integrated development environments (Integrated Development Environment, IDE) PSoC Creator, Arduino IDE. All the specified software products do not require a license fee and are freely available for students.
