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.

__Contact outside lecture hours: __In the department, you can find me in II-303. Phone: 1085 email: mamidala@ieee.org Home: www.mjkumar.net

__Final Pointers__

1. Coming to the class **on time** is very essential.

2. You must clarify your doubts during the lecture or at the very least immediately after the class.

3. Practice solving as many problems from the text books as possible.

4. Always keep a calculator with you in the class.
