# Massachusetts Institute of Technology: Circuits and Electronics 2: Amplification, Speed, and Delay

Learn how to speed up digital circuits and build amplifiers in the design of microchips used in smartphones, self-driving cars, computers, and the Internet.

5 weeks
7–9 hours per week
Self-paced
Free

Want to learn how to construct an amplifier for mobile phones? Wondering how energy storage elements like capacitors and inductors work, or how to make microchips run faster? This free circuits course taught by edX CEO and MIT Professor Anant Agarwal and colleagues is for you.

This is the second of three online Circuits and Electronics courses and is taken by all MIT Electrical Engineering and Computer Science (EECS) majors.

Topics covered include: MOSFET large signal and small signal analysis; amplifiers; energy storage elements like capacitors and inductors; and dynamics of first-order networks and circuit speed. Design and lab exercises are also significant components of the course.

Weekly coursework includes interactive video sequences, readings from the textbook, homework, online laboratories, and optional tutorials. The course will also have a final exam.

This is a self-paced course, so there are no weekly deadlines. However, all assignments are due when the course ends.

" Brilliant course! It's definitely the best introduction to electronics in Universe! Interesting material, clean explanations, well prepared quizzes, challenging homeworks and fun labs." - Ilya.

" 6.002x will be a classic in the field of online learning. It combines Prof. Agarwal's enthusiasm for electronics and education. The online circuit design program works very well. The material is difficult. I took the knowledge from the class and built an electronic cat feeder." - Stan

Where can I buy the textbook for this course?
You may purchase the physical textbook or its ebook from Elsevier. An online version of the book will also be accessible for free to students who upgrade to the verified certificate track in the course. **

Will the text of the lectures be available?**
Yes, transcripts of the course will be made available.

Do I need to watch the lectures live?
No. You can watch the lectures at your leisure.

I don't have the prerequisites, can I still take the course?
We do not check students for prerequisites, so you are certainly allowed to try. However, 6.002.2xdoes depend on previous experience with electricity and magnetism, and differential equations. If you do not know those subjects before taking the class, you will have to learn them over the semester, which can be a difficult task.

# Who can take this course?

Unfortunately, learners residing in one or more of the following countries or regions will not be able to register for this course: Iran, Cuba and the Crimea region of Ukraine. While edX has sought licenses from the U.S. Office of Foreign Assets Control (OFAC) to offer our courses to learners in these countries and regions, the licenses we have received are not broad enough to allow us to offer this course in all locations. edX truly regrets that U.S. sanctions prevent us from offering all of our courses to everyone, no matter where they live.
