Week 10: Operational Amplifiers

Having learned the basic laws and theorems for circuit analysis, we are now ready to study an active circuit element of paramount importance: the operational amplifier, or op-amp for short.

It can also be used in making a voltage or current-controlled current source. An op-amp can sum signals, amplify a signal, integrate it, or differentiate it. The ability of the op-amp to perform these mathematical operations is the reason it is called an operational amplifier. It is also the reason for the widespread use of op-amps in analog design. Op-amps are popular in practical circuit designs because they are versatile, inexpensive, easy to use, and fun to work with.

We will begin this lesson by discussing the ideal op-amp and later consider the nonideal op-amp. Using nodal analysis as a tool, we consider ideal op-amp circuits such as the inverter, voltage follower, summer, and difference amplifier.
