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.
