Operational Amplifiers

There is unity gain in this configuration because of the non-inverting properties of the Op Amp. To change the gain, the feedback network must be changed to include two other resistors (R2 and R3). The gain is then found to be 1 + R3/R2 because of the non-inverting configuration. The circuit with a non-unity gain is shown in Figure 2. (1) ................
