There will be four quizzes. These will count for 50-60% of the grade and the end semester exam for the remaining 40%. Biweekly tutorials will count for up to 10% of the grade.

The recorded lectures are available here. You can also find lectures from previous years at the same link. The NPTEL online course Analog Circuits also covers a portion of the material.

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. (The dates below are only tentative ones and can be changed at any time)

• Problem set 1: 1 September 2015
• Problem set 2: 2 September 2015
• Problem set 3: 9 October 2015
• Problem set 4:
• Problem set 5: 30 October 2015
• Problem set 6: 16 November 2015
• Problem set 7: 16 November 2015(Problem 1-5, 10-12, 15-16 will be marked)
• Problem set 8:

• Nonlinear one-port and two-port circuits; Large signal and small signal incremental analysis; Incremental y parameters for obtaining gain; nMOS transistor;

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.
