3148 Semiconductors
ECTS credits: 5
Weekly classes: 3lec+0sem+2labs+0ps+p
Assessment: exam
Type of exam: written
Department involved:
Department of Electronics
Faculty of Electrical Engineering, Electronics and Automation
Lecturers:
Principal Assistant Krasimira Stefanova Shtereva MEng, PhD, Dept of Electronics,
tel.: 888 381, Е-mail: KShtereva@ecs.uni-ruse.bg
Abstract:
The course aims to familiarize the students with the main active semiconductors. It covers the physical principles
of operation, structure, characteristics and the parameters of the discrete elements. The course deals with the
practical application of semiconductors, the ways to connect them in electronic circuits and calculate their working
modes.
Course content:
Physical principles used in semiconductors. Semiconductor diodes. Semiconductor voltage – regulator diodes.
Tunnel diodes. Bipolar transistors: characteristics, parameters of the transistors as quadripole, frequency
characteristics of the transistors; dynamic and key operation mode of the transistor. Field-effect transistors: fieldeffect
transistors with p-n junction. MOS-transistors. Thyristors. Optoelectronics. Principles of microelectronics;
types of integrated circuits; fundamentals of constructing bipolar and МOS – integrated circuits.
Teaching and assessment:
The lectures provide the theoretic aspects of the topics. Each lecture is supported by visual materials such as
slides. Laboratory work involves 4 classes every second week and the whole sub-group does the same
assignment. Each assignment is supported by a report which is defended before the lecturer. The results of
students’ performance are taken into consideration when forming the final mark at the exam. It is written and
involves two questions from the syllabus followed by an oral quiz.

Abstract:
The Theoretic Electrical Engineering 2 course familiarizes the students with the main methods for analysis of
settled and transient processes in a chain with distributed parameters and in non-linear electric chains and with
the methods of analysis of electric fields.
Course content:
Chains with distributed parameters - main concepts, differential equations of a homogeneous line, settled sine
process in a homogeneous line, input impedance, line with no losses, standing waves. Non-linear electric chains -
constant modes, main laps and methods for analysis, periodic modes, electric chains inertia and non-inertia nonlinear
elements, analysis methods, resonance phenomena, transient processes, methods. Theory of
electromagnetic field – Maxwell’s equations, scalar and vector potential, intensity of electric field, constant and
magnetic fields in polarizing environments, potential fields, equations of Poisson and Laplace, Furrier’s method,
method of mirror images, of complex variable function, polarized ellipsoid, potential and charge equations, partial
capacities, electromagnetic parameters, capacity, inductivity, mutual inductivity, transforming the energy of electromagnetic
field, Pointing theorem, transmitting energy over a two-wire line and transformer connection, alternating
electro-magnetic fields, electromagnetic potentials, D’Alambere’s equations, emitting electro-magnetic waves.
Teaching and assessment:
The continuous assessment is conducted at the laboratory exercises by an oral discussion and submission of
reports. The final assessment is done at the exam (written and oral), which consists of solving problems and
answering questions.
