This course is on Operational Amplifier. Here we shall discuss various concepts on Operational Amplifier like virtual ground concept etc. and also look at various configurations of Opamp like Inverting Opamp, Non-Inverting Opamp, Summing Amplifier, Differentiating Amplifier, Integrating Amplifier etc. We will also look at parameters like CMRR, Sler Rate etc.

Test Preparation

This is an introduction to the course on operational amplifier, and I have summarised the topics that I shall explore in the course.

Course Overview (in Hindi)

In this lecture, we look at the various definitions and the kind of working of an opamp. This is just an introduction. We shall go deeper into these concepts and definitions in our subsequent lectures.

Introduction to Operational Amplifier (in Hindi)

In this lecture, we have shown how a differential amplifier works in differential mode as well as common mode. We define the CMRR and explain why it is important for an amplifier.

Common Mode and Differential Mode (in Hindi)

In thus lecture i have explained the concept of virtual ground and tge assumption that no current flows into the Op-Amp. Both the concept and the assumption are important to solve sums, and most of the time they are not clearly understood, hence I have explained them in a separate video.

Virtual Ground Concept (in Hindi)

In this lecture, we have shown how the operational amplifier acts as a differential amplifier and guves us the required output voltage.

Prime Gate Institute

In this course we are going to learn passive and active Filters in depth.
We will study concept behind all the Filters and then will see techniques to identifying types of filters. Then we will solve GATE Previous Year Problems of ECE EE and IN.

(Hindi) GATE (ECE): Active and Passive Filters

In this course we are going to study, How to solve an op-amp problems when it is in negative feedback configuration, if is an ideal op-amp and if it operates in linear region. Please watch it once. It will be very much helpful for GATE/ESE/PEU's.

Problem Solving Techniques for Op-Amp: GATE(ECE)

I am a student of third year and I am preparing for GATE 2019! I always wanted to teach and now Unacademy has given me a chance!

Milind S

In this course, the educator discusses how to solve problems on OP-AMPS. The course will be beneficial for GATE (ECE) aspirants.

Operational Amplifiers: GATE (ECE)

This course is on operational amplifier. Here we shall discuss the various concepts of operational amplifier  like virtual ground concept etc., and also look at various configurations of opamp like inverting opamp, non inverting opamp, summing amplifier, differentiating amplifier, integrating amplifier etc. We will also look at parameters like CMRR, Sler Rate etc.
