FAQs on Introduction to Operational Amplifier Video Lecture - Analog and Digital Electronics - Electrical Engineering (EE)

1. What is an operational amplifier (op-amp)?
Ans. An operational amplifier, or op-amp, is a type of electronic amplifier with a high gain used in signal processing and analog computations.
2. What are the key characteristics of an operational amplifier?
Ans. The key characteristics of an operational amplifier include high input impedance, low output impedance, high gain, and differential inputs.
3. How is the ideal op-amp model represented in circuit diagrams?
Ans. The ideal op-amp model is represented in circuit diagrams with a triangle symbol with two input terminals and one output terminal.
4. What are some common applications of operational amplifiers in electrical engineering?
Ans. Some common applications of operational amplifiers include signal amplification, signal filtering, voltage-to-current conversion, and instrumentation amplifiers.
5. How can negative feedback be used to stabilize the operation of an operational amplifier?
Ans. Negative feedback can be used by connecting a portion of the output signal back to the inverting input terminal to stabilize the operation of an operational amplifier and control its gain.
