- Understanding of MOS transistors: Focus on the behavior relevant to analog circuit design.
- Develop design intuition: Feel for tradeoffs – noise, dynamic range, power.
- Design based on hand calculations: Avoid perpetual “tweaking” in SPICE.
- Gain hands-on design experience: High performance amplifier design project.

- Introduction and Basic Concepts: analog vs digital, applications of analog ICs, CMOS technology and devices, device mismatch and errors, MOS transistor behavior, noise in passives & MOSFETs, systematic design procedure for basic amplifier.
- Advanced Topics: multi-stage amplifiers, compensation techniques & loop stability, transient response in amplifiers, designing amplifiers for transient response Gm-C integrators.
- Special Topic: switched-capacitor circuits.

Problem sets will be posted below. You are expected to solve them on your own. You can approach the teaching assistants for clarifications and help. You should work each one before the corresponding dates given below.

This course doesn't follow a single textbook. You can follow any of the references below for different sections of the course.

- Behzad Razavi,
*Design of Analog CMOS Integrated Circuits*, McGraw-Hill, August 2000. - Carusone, Johns, and Martin,
*Analog Integrated Circuit Design*, 2nd ed., Wiley, 2000. - Gray, Hurst, Lewis, and Meyer,
*Analysis and Design of Analog Integrated Circuits*, 5th ed., Wiley 2009.

This course will mostly follow the lines of NPTEL course whose link is given below.

Knowledge of negative feedback control systems is essential for a good understanding of circuits. The book below is a very good reference. Chapters 8, 9, and 10 are particularly relevant to us.

- Astrom and Murray,
*Feedback Systems: An Introduction for Scientists and Engineers*, Available: http://www.cds.caltech.edu/~murray/amwiki/index.php/Main_Page

If you are little rusty on basic circuit analysis or laplace transforms, refresh them from the references below or any of the widely used textbooks. In particularly, we will use Bode plots and Laplace transforms widely-they are described at the last two links below.

- Circuit analysis with Laplace Transforms: Follow lectures 5-8 at this link to refresh your understanding of laplace transform analysis, sinusoidal steady state etc. Solve the practice problems in this problem set.

Attendance will be strictly enforced and those falling short will not be permitted to write the end sem exam. TAs will go around the room taking attendance at the beginning of the class. If you are more than 5 min. late, please do not enter the classroom. }
