Course description and aims

As fundamentals for design of computer architectures, basics of computer hardware such as functions and characteristics of MOS transistor and constitution of logic gates are given. Mathematics and theories to understand logic circuits such as Boolean algebra, characteristics of logic functions, sequential circuit are studied. With these background knowledge, design techniques for logic and sequential circuits, simplification, unification and decomposition of the circuits are studied.

Student learning outcomes

Binary operation of MOS transistor is studied. It is applied to constitute logic gates and their characteristics are studied. Designing techniques for logic and sequential circuits are studied with simplification, unification and decomposition methods.


MOS transistor, Logic gate, Logic circuit, Boolean algebra, Sequential Circuit and Simplification of logic circuits

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Lecture and reports to check the understanding. Lecture is given through active-learning and interactive discussions between lecturers and students. Evaluation is done by the reports, interaction and participation in the lecture, and the final exam.
