Outline

In this course, we will discuss the design of analog circuits on integrated circuits. Realization of negative feedback circuits is a common thread to all the circuits that we see in this course. We will start with a discussion of components available on CMOS ICs, their modeling, and layout. We will then discuss noise and mismatch, which limit circuit capabilities in some ways. We then discuss negative feeback systems and their stability, and various opamp types(single stage, cascode, multi-stage, and their fully differential versions) used to realize negative feedback systems on a chip. Similar attempts to realize a frequency multiplier using negative feedback will lead us to the phase locked loop. We will analyze the main types of PLLs, and derive their incremental phase domain models commonly used for analysis. After these, we will look at bandgap references, voltage regulators, and current references as additional examples.

References

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

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.

Pre-requisites

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.

Attendance

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.
