Unit IX: The Operational Amplifier | BCA 2nd Semester Fundamentals of Electrical and Electronics Notes Pdf

An operational amplifier, or op-amp for short, is a voltage amplifier having external feedback components like resistors and capacitors between its output and input terminals. Because of the numerous feedback topologies, whether resistive, capacitive or both, the amplifier may execute a number of different functions, earning it the nickname "Operational Amplifier."

A three-terminal device with two high impedance inputs is known as an operational amplifier. The Inverting Input, denoted by a negative or "minus" symbol ( – ), is one of the inputs. The Non-inverting Input, denoted by a positive or "plus" sign ( + ), is the other input.

The operational amplifier's output port, which may both sink and source voltage or current, is represented by a third terminal. The output signal of a linear operational amplifier is the amplification factor, known as the amplifier's gain ( A ), multiplied by the value of the input signal, and there are four distinct types of operational amplifier gain depending on the nature of the input and output signals.

In this “The Operational Amplifier – Fundamentals of Electrical and Electronics” you will learn about the following topics:

1. The Operational Amplifier
2. The Ideal Operational Amplifier and Its Characteristics
3. Inverting and Non-Inverting Amplifiers
4. Summing Amplifier
5. Integrating and Differentiating Amplifiers
