• Assignments and Projects (20%)
• Quiz-I (20%)
• Quiz-II (20%)
• Final Exam (40%)

• Understanding of MOS transistors: Focus on the behavior relevant to analog IC 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, Fully Differential Opamps.
• (Possible) Special Topics: Phased Locked Loops, Bandgap References, Switched capacitor circuits; High-speed amplifiers etc

All simulation assignments/projects will be done on LTSpice (https://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html). If you have access to another circuit simulator such as Spectre or Eldo through another course or through your research lab, you are welcome to use that simulator. Some simple simulation exercises for practice are listed below to get you started.

• LTSpice Simulation exercises
• Other simulation exercises for practice)

For the assignments and projects, use the TSMC 0.18 um MOSFET Model Files from: http://www.ee.iitm.ac.in/~nagendra/cadinfo.html

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.
• The Design Of CMOS Radio-Frequency Integrated Circuits by Thomas H. Lee (Publisher: Cambridge University Press - 2006)
• 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.

• NPTEL course on Analog IC Design

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

• Analog Circuits

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.

• Electrical and Magnetic Circuits
• Networks and Systems
• Bode plots: Recorded lectures here and here
• 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 as per the latest IITM rules and regulations. Those falling short will not be permitted to write the end sem exam.
