The full analysis of the op-amp circuits as shown in the three examples above may not be necessary if only the voltage gain is of interest. This is based on the assumptions that is in the range between the positive and negative voltage supplies e. If one of the two inputs is grounded, the other one is also approximately grounded, called virtually grounded. If none of the two inputs is grounded, their voltages can still be assumed to be virtually the same. Based on this assumption, the analysis of all op-amp circuits is significantly simplified. However, note that if the input and output resistances of the op-amp circuits are of interest as well, the full analysis shown previously is necessary.
The author clearly explains how to use the.
