Modern society is supported by electronics technologies such as computers, mobile phones, and home appliances. Electronic
circuits support the foundation of this electronics technology. Elements such as transistors have evolved into ICs, LSIs,
and VLSIs, and technological innovation is progressing at an exponential speed. Therefore, it is very difficult to understand
all the electronic devices composed of the most advanced electronic circuits. In this lecture, students will learn how to
analyze the operating principle of electronic circuits that make up electronic devices from basic elements.
In this lecture, students will learn how to convert a low-frequency basic amplifier circuit to an equivalent circuit using
transistors and FETs, actually perform the conversion, and acquire the ability to understand the operating principle by analyzing
it. In addition, after fully understanding the operating principles of low-frequency circuits, acquire the ability to understand
and analyze the extended high-frequency circuits. Furthermore, the purpose is to fully understand these basic matters and
acquire the ability to understand the operating principles of new elements and circuits.
- Students can review the basic knowledge of electric circuits and get a peculiar basic idea of electronic circuits.
(Week 1) - Students can understand the operating principle of transistors and FETs and the equivalent circuit.
Students can understand the operating principle of the basic amplifier circuit, convert it to a large signal equivalent circuit or a small signal equivalent circuit, and analyze the circuit.
(Weeks 2-7) - Students can understand the conversion of the basic amplifier circuit to a small signal equivalent circuit by the high frequency
small signal model and the outline of the frequency characteristics.
(Weeks 8-9) - Students can understand the principle and effect of negative feedback and analyze the negative feedback circuit.
