The Ideal Op-Amp
- 68 Downloads
An operational amplifier (op-amp) is a special type of differential amplifier that has some very useful properties. Op-amps are available as inexpensive self-contained integrated circuits and the detail of what goes on inside the device is rarely of concern. In this chapter, the ideal op-amp, treated as a device, is introduced and many useful circuits based on the ideal op-amp with feedback are presented. After that, some discussion of properties of a real op-amp are presented.
