When analyzing operational amplifiers, there are a few rules that need to be taken into consideration in order to solve circuits using KVL or KCL.
- Because the output voltage does not depend on the output current, the output impedance equals zero.
- The input impedance .
- When there is a negative feedback, both inputs have the same voltage. In other words, is equal to .
- When solving circuits using the nodal analysis, write node equations at and , but not at .
