Introduction This tutorial is an introduction to the Operational Amplifiers, also known as op-amps. The fundamental goal of op-amps is to amplify a voltage difference and it is the reason why we also describe them as differential amplifiers. Op-amps have been invented the exact same year as the transistors (1947) and they were originally designed […]
