For an ideal operational amplifier (except for the fact that it has finite gain) one set of the value for the input voltages (v2 is the positive terminal v1 is the negative terminal) and output voltage (v0) as determined experimentally is v1= 2.01V, v2=2.00V and v0= -0.99V. Experiment was carried with different values of input and output voltages. Which of the following is not possible considering experimental error? |
| A. | v<sub>1</sub>= 1.99V, v<sub>2</sub>= 2.00V, v<sub>0</sub> = 1.00V |
| B. | v<sub>1</sub>= 1.00V, v<sub>2</sub>= 1.00V, v<sub>0</sub> = 0V |
| C. | v<sub>1</sub>= 1.00V, v<sub>2</sub>= 1.10V, v<sub>0</sub> = 10.1V |
| D. | v<sub>1</sub>= 0.99V, v<sub>2</sub>= 2.00V, v<sub>0</sub> = 1.00V |
| Answer» E. | |

Express the input voltages v1 and v2 in terms of differential input (vd) and common-mode input(vc). Given v2 > v2. |
| A. | V<sub>d</sub> = V<sub>1</sub> V<sub>2</sub>, V<sub>c</sub> = 0.5(V<sub>1</sub> + V<sub>2</sub>) |
| B. | V<sub>d</sub> = V<sub>2</sub> V<sub>1</sub>, V<sub>c</sub> = V<sub>1</sub> + V<sub>2</sub> |
| C. | V<sub>d</sub> = V<sub>1</sub> V<sub>2</sub>, V<sub>c</sub> = V<sub>1</sub> + V<sub>2</sub> |
| D. | V<sub>d</sub> = V<sub>2</sub> V<sub>1</sub>, V<sub>c</sub> = 0.5(V<sub>1</sub> + V<sub>2</sub>) |
