Linear Integrated Circuits

By Dr. Yedukondala Rao Veeranki | NIT Puducherry

Learners enrolled: 335

This course provides a comprehensive understanding of linear integrated circuits and their diverse applications. It begins with the fabrication techniques and internal configurations of ICs, including transistors, resistors, capacitors, and current sources. Students explore the fundamental building blocks of operational amplifiers, their characteristics, and typical configurations. The course delves into various op amp applications, analog multipliers, phase-locked loops (PLLs), and data converters (A/D and D/A). It also covers waveform generators and specialized ICs such as timers, regulators, and signal converters. Emphasis is placed on practical applications and circuit analysis relevant to modern analog electronic systems.

Course certificate

"The SWAYAM Course Enrolment and learning is free. However, to obtain a certificate, the learner must register and take the proctored exam in person at one of the designated exam centres. The registration URL will be announced by NTA once the registration form becomes available. To receive the certification, you need to complete the online registration form and pay the examination fee. Additional details, including any updates, will be provided upon the publication of the exam registration form. For more information about the exam locations and the terms associated with completing the form, please refer to the form itself."

Grading Policy:

- Internal Assignment Score: This accounts for 30% of the final grade and is calculated based on the average of the best three assignments out of all the assignments given in the course.

- Final Proctored Exam Score: This makes up 70% of the final grade and is derived from the proctored exam score out of 100.

- Final Score: The final score is the sum of the average assignment score and the exam score.

Eligibility for Certification:

- To qualify for a certificate, you must achieve an average assignment score of at least 10 out of 30, and an exam score of at least 30 out of 70. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >=40/100.

Certificate Details:

- The certificate will include your name, photograph, roll number, and the percentage score from the final exam. It will also feature the logos of the Ministry of Education, SWAYAM, and NITTTR.

- Certificate Format: Only electronic certificates (e-certificates) will be issued; hard copies will not be dispatched.
