Analog Electronic Circuits

This course on Analog Electronic Circuits has been designed primarily as a core course for undergraduate students and, as a refresher course for master level students and circuit designers working in industry. It starts with basic circuit components and circuit concepts and then, gradually moves to practical building blocks of analog electronic systems. In this course, a serious attempt has been made to make a balance between theory and practice so that the discussed circuits can be constructed in an undergraduate level laboratory class and their measured performance can be easily compared with the analytically predicted performance. It helps to build confidence on theory. 
The other important feature of this course is, it covers both BJT based circuits and MOSFET based circuits parallel so that similarities and performance differences between these two classes of circuits are understandable. Moreover, the BJT based circuits discussed here can be easily constricted on bread board to verify their characteristic through measurement. On the other hand, analysis of the MOSFET based circuits provides the necessary foundation for Analog VLSI circuit/system design, a next level course in Microelectronics and VLSI Design. 
The above mentioned two features make the proposed course unique with respect to the existing NPTEL courses on this topic. Further, the content of the proposed course is well aligned to the content of Analog Electronics course (EC09) under “AICTE Model Curriculum for undergraduate degree in Electronics and Communication Engineering (Engineering & Technology) published in 2018

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 24 April 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score
