Summary

The ideal op-amp works like a Voltage Controlled Voltage Source (VCVS), where the output voltage is equal to the difference in input voltages multiplied by a large open-loop gain.


Description

This example is from the The Ideal Op-Amp (Operational Amplifier) chapter of Ultimate Electronics Book.

The ideal op-amp works like a Voltage Controlled Voltage Source (VCVS), where its output is equal to the difference of its inputs multiplied by a large open-loop gain A_OL.

Modeling the op-amp as a VCVS is a very powerful technique that makes it possible to design and analyze complicated op-amp circuits.
