The purpose of this class is to understand the properties of semiconductors and to be able to analyze the operation of transistors
which is the fundamental building blocks of electronic circuits, as well as analyze and design basic amplifier circuits and
oscillator circuits.
Electronic circuits include analog and digital circuits, but this course focuses primarily on analog circuits. Building upon
the knowledge acquired in “Fundamentals of Electrical Circuits,” students will gain an understanding of various semiconductor
devices that constitute analog circuits. They will also learn the operating principles and analysis methods of amplifier circuits,
which form the basis of analog circuit design. Furthermore, students will study the operating principles and specific examples
of oscillator circuits, which are derivative forms of amplifier circuits, as well as power supply circuits.
The circuits covered in this course are fundamental and essential components used in various communication devices. They form the foundation for the specialized knowledge in information and communication engineering that students will acquire in future studies.
