Basics of Operational Amplifiers

Introduction – Operational Amplifier Operational-amplifiers is basically amplifier. And the basic job of an amplifier is to amplify the input signal. Why operational amplifiers ? As the name itself suggests operational, operational amplifier performs different mathematical operations. For example addition, subtraction, integration, and differentiation. So, just by connecting few resistors and capacitors, it is possible …
