This lecture is highly recommended for anyone who wants a true understanding of analog circuit design. Going beyond the level of simply memorizing theory, it is designed to help you develop the ability to think for yourself and solve problems, so you can feel a depth that is differentiated from undergraduate lectures or other special lectures. In particular, the ability to directly design circuits that are essential in the field, such as LDOs, Comparators, and Charge-Pumps, and to experience performance improvements is a really great strength. In addition, thanks to Samcoachi's Naver Cafe, which provides additional learning support in addition to the lecture, continuous growth was possible beyond simply taking the course. I am confident that this lecture is the best class for those who are considering a career in the analog and mixed signal fields.
