The 0s and 1s we talk about, HIGH and LOW, logic gates and flip-flops— they all emerge from the physical event of analog signals crossing a threshold. If so, wouldn't understanding the world before logic— the movements created by current and voltage— be the true beginning of circuit design? This course takes that first step together.

I'm a junior majoring in Physics. I've always been interested in analog circuits and wanted to pursue a career in that field, so I searched for and took this course. The instructor explained everything from basic analog circuit concepts to OP-AMP operating principles and applications in an easy-to-understand and kind manner, and also showed how to apply them in actual circuits, which was very helpful. I hope this course becomes widely known to people like me who are interested in analog circuits or whose career path is related to this field~

It was a confusing part, but your explanation was so good that I understood it well.

I am currently working in the electrical field, not electronics. (In the past, I also worked in firmware. Since I didn't major in electrical or electronic engineering, I struggled a lot in the beginning. TT) I often see juniors who focus solely on the formulas themselves, but when asked about physical characteristics, they don't really understand the essence or can't answer immediately. For example, when looking at the capacitive reactance formula $1/(2\pi fC)$, I tell them that rather than just memorizing the formula, they should first get a feel for it: "Since a capacitor's reactance decreases when the change in electricity is large, noise with a high frequency will be effectively removed through a capacitor connected to the ground." I explain that understanding this intuition before memorizing the formula allows them to solve problems faster in practice later on. I believe this lecture is excellent because it focuses more on the fundamental properties of circuits rather than just the formulas. (When I studied, I used formulas to infer basic properties, but the difference here is that this lecture starts with the basic properties first.) However, because it helps you see the essence first and lacks formulas, those who want to study more deeply might find it too simple. It seems difficult to apply the content to practical work based on this alone (I think it's impossible to make practical application possible through a one-and-a-half-hour lecture). Explanations of formulas, inferring basic circuit properties through those formulas, and practical application methods definitely need to be supplemented. I kindly request that you cover these topics in the intermediate class.

I personally designed a 12-bit SAR ADC,
I performed LVS/DRC verification and chip fabrication within the Synopsys environment,
I have gained a deep understanding of the connection between theory and actual circuitry.
In this course, based on that experience, we will build a "foundational base for moving from analog through digital to ASIC design" together.
In this lecture, based on that experience,
“Building the fundamental foundation that progresses from analog through digital to ASIC design” together..

Hello! Thank you so much for taking the time to leave such a thoughtful review. With your physics background, you must have a solid theoretical foundation, and I'm truly proud as an instructor to hear that my 'intuitive approach' helped you understand OP-AMP operating principles and practical applications. While analog circuit design can feel like it has a high barrier to entry, I'm confident that with your perspective of seeing through to the 'physical essence' as you do now, you'll become an excellent engineer. If you encounter any difficulties while studying, please feel free to post questions on the Q&A board anytime. I sincerely support your career path! Fighting!

NEKO, thank you for your valuable review! You're right. When studying circuits, the formulas often obscure the real principles, which can be very confusing. 😅 I'm truly happy as an instructor to hear that my explanation helped clear up those frustrating parts for you. I'm rooting for you to design circuits with confidence and no more confusion!
