### Course description and aims

While digital circuits have dominated large-scale integrated circuits, cutting-edge analog circuit technology is indispensable for high-speed wireless communication system, signal processing, etc. In this course, the fundamental characteristics of transistors (bipolar and field effect transistors), which are required for design of analog circuits, are first explained. Then, the small-signal equivalent circuit models of transistors are studied. The amplification mechanism and frequency characteristics of amplifier circuits using transistors in various configurations are examined. Variation in transistor characteristics, noise sources in circuits, and nonlinear behaviors are also introduced. The principles and design methods for various transistor circuits such as the current mirror, differential amplifier, negative feedback, operational amplifier, and oscillators are studied.
The course objectives are as follows: understanding the basic characteristics of transistors (bipolar transistor and field effect transistor), learning the equivalent circuits of transistors, understanding the amplification mechanism and frequency characteristics of transistor amplifier circuits, and learning the principle and design methods of various transistor circuits.

 ✔ Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills ✔ ・Fundamental specialist skills on EEE

### Class flow

At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Students then learn the analog circuits during the lecture. Toward the end of class, students will be given new exercise problems related to the lecture given that day to solve. Students should review previous classes and prepare for the next class in advance.
