Analog Electronics Circuits
Objective of the course: To familiarize and develop skills in the design and analysis of Analog Electronic Circuits which form the building blocks of almost any electronic system.
Structure of the course: This course primarily deals with the operation and application of transistors as amplifying or controlling devices. The lectures are aimed to guide you think about the design, performance and limitations of analog electronic circuits commonly used in ICs. You are expected to participate in the class not only in terms of raising questions and answering them but also in terms of applying what you learn to contrived and real world problems.

Your feedback is valuable:
Please note that your feedback on any aspect of this course will be greatly appreciated. Any time, you can talk to me to give your informal feedback. However, I will be taking two written feedbacks from you - one just after Minor-I and the other, a week before the Major. I expect you to be objective and enthusiastic to give your feedback.
