«Electronics Ι» is the first part of a two‐semester curses. It is dedicated to the principles of analog
electronic circuits.
Starting with the atomic structure of semiconductors, the syllabus continues with the main
characteristics of the pn junction, diode biasing and characteristics, the main rectifier circuits, and
power supply filters and regulators. It also contains elements of the Bipolar Junction Transistor (BJT)
structure, BJT bias circuits and their function as small signal amplifiers and switches.
Electric circuit design and analysis is based on theoretical calculations assisted by a powerful
computer simulating tool, MultiSim.
On successful completion of this module the learner will be able to:
• Explain how to bias a diode and describe its IV characteristic curve.

• Design and analyze the operation of three basic rectifier circuits: half-wave rectifier, center-
tapped and bridge full wave rectifier.

• Describe the function of power supply filters and regulators.
• Describe the three types of BJT bias circuits: base, voltage divider and emitter.
• Design and analyze the operation of a BJT as a small signal amplifier.
• Use a BJT in a switching circuit.

The grade of the course theory derives from the
grade of the written examination as well as that
of the possible progress exams. The grade of the
course laboratory is that of the final exam
(Project), in which the quality of the delivered
assignments is taken into account qualitatively.
The final grade of the course is calculated
indicatively based on the following equation.
Final grade = 0.75 (Theory grade) +0.25
(laboratory grade), if (THEORY grade) ≥ 5.
