### 课程概况

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.

### 课程大纲

Week 1: Amplifiers, MOSFET large signal analysis, MOSFET small signal analysis
Week 2: Capacitors, first-order RC circuits
Week 3: Inductors, first-order step response, first-order circuit analysis, impulses, digital circuit speed
Week 4: Impulse, step, ramp superposition, digital memory, state, ZIR, ZSR

### 预备知识

You should have a mathematical background of working with calculus and basic differential equations, and a high school physics background in electricity and magnetism. You should also have taken Circuits and Electronics 1, or have an equivalent background in basic circuit analysis.

### 常见问题

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.
