Test Preparation

This lesson is the overview of the topic:Operational Amplifier in which we have learnt the topics which we are about to discuss in this course.

Overview

In this lesson I have explained the Topic Analysis which emphasizes the importance of this topic in GATE exam or any other exam in general.

Preparation Strategy

In this lesson I have explained the Intern Structure of Op-Amp where we have understood the first stage i.e., Differential Amplifier stage in detail.

Internal Structure:Part-1

In this lesson I have explained the remaining stages of Internal Structure of Op-Amp in which we have understood the usage of Level-Shifter and Power Amplifier.

Internal Structure:Part-2

In this lesson I have explained some important Characteristics of the topic Operational Amplifier where we have understood the fact that Op-Amp is a Direct Coupled Amplifier.

Op-Amp Characteristics

In this lesson I have explained the pin Diagram of Op-Amp and some important Properties like:High Open loop gain, Equivalent circuit of Op-Amp and Input and Output resistances..

Properties of Op-Amp

In this lesson I have explained some important Properties of Op-Amp which includes Open Loop Bandwidth and Common Mode output.

Properties of Op-Amp:Part-2

In this lesson I have explained the concept and Derivation of CMRR(Common Mode Rejection Ratio) in detail.

Properties of Op-Amp(Part-3)

In this lesson I have explained the concept of one of the most important property of Op-Amp:Slew Rate with the help of an example.

Slew Rate

This lesson is dedicated to the concept of Virtual Short and Virtual Ground with some important exceptions..!!!

Virtual Short and Virtual Ground

In this lesson I have explained the concept of Transfer Characteristics of ideal Op-Amp as well as the Practical Op-Amp in detail with an important conclusion at the end.

Transfer Characteristics of Op-Amp

In this lesson I have explained the Negative Feedback Applications: Inverting Amplifier in which I have discussed the Ideal as well as Practical cases in detail.

NEGATIVE FEEDBACK APPLICATIONS: Inverting Amplifier

In this lesson I have explained the Negative Feedback Applications: Non-inverting Amplifier in which I have explained the concept of Ideal as well as Practical cases in detail.

Negative Feedback Applications: Non-inverting Amplifier

In this lesson I have explained the Input and Output impedances of Inverting and Non-inverting Amplifiers and I have also discussed a GATE previous year question based on this topic.

Input and Output Inpedances of Inverting and Non-inverting Amplifiers

In this lesson I have discussed about the Inverting Summing Amplifier and Non-Inverting Summing Amplifier in detail along with their respective formulae.

Inverting and Non-Inverting Summer Circuits

In this lesson I have discussed the concept of Adder/Subtractor with the respective formula and a GATE previous year question associated with the concept of Summing Amplifiers.

Adder/Subtractor

In this lesson I have discussed the concept of the Voltage Follower and have also explained as how this circuit acts as a Buffer Circuit to prevent the Loading Effect.

Voltage Follower

In this lesson I have explained the concept of Difference Amplifier in which I have discussed its closed loop gain,input impedance and later have seen some major disadvantages.

Difference Amplifier

In this lesson I have discussed some GATE previous years questions based on the topic: Difference Amplifier in which I have explained the techniques of solving them.
