# Operational Amplifiers: Linear Integrated Circuits

via Udemy

### Overview

Learn the concepts of OP AMPs from Linear Integrated Circuits and solve problems!

What you'll learn:
• Understand the concepts of OP AMPS
• Know how to apply principles of electrical engineering for the circuits involving op amps
• Using IC741, Build different analog circuits
• Solve Problems on Linear Integrated Circuits

The course deals with having a complete understanding on IC741 - Operational Amplifiers, as a part

of Linear Integrated Circuits.

To understand the concepts, there is a video on 'A review on Network Theory'

The following are the contents discussed:

1. What is IC741?

2. Ideal characteristics of OP AMP

3. Open loop configuration of OP AMP

4. The concept of virtual short and virtual ground

5. Closed loop configuration - Inverting Amplifier, Non Inverting Amplifier

6. DC Characteristics

7. AC Characteristics - Slew Rate

8. Applications - Voltage Follower, Bufer,

9. Log and Antilog Amplifier, Analog Amplifier

10. Differentiator, Integrator

11. Non Linear Applications - Half Wave Rectifier

12. Open Loop Comparator

13. Zero Crossing Detector

Problems on OP AMPs from competitive examinations will also be solved.

An operational amplifier, or op-amp for short, is a voltage amplifier with external feedback components such as resistors and capacitors connected between its output and input terminals. These feedback components determine the amplifier's final function or "operation," and the different feedback topologies, whether resistive, capacitive, or both, allow the amplifier to execute a wide range of operations, earning it the name "Operational Amplifier."

Operational amplifiers have a large open loop DC gain on their own, but by using Negative Feedback, we can create an operational amplifier circuit with a very accurate gain characteristic that is only dependent on the feedback employed. The term "open loop" refers to the absence of any feedback components around the amplifier, implying that the feedback line or loop is open.

• Shivakumar Duduri
The course "Integrated Circuits, MOSFETs, OP-Amps and Their Applications" by NPTEL via YouTube is a comprehensive introduction to these crucial components in electronics. The lectures are well-structured, covering theory and practical applications effectively. However, some topics could benefit from more detailed explanations. Overall, a valuable resource for understanding and applying these concepts in electronics design and engineering.
