D2.7 Design an inverting op-amp circuit to form the weighted sum vO of two inputs v1 and v2. It is required that vO = −(v1 + 4v2). Choose values for R1, R2, and Rf so that for a maximum output voltage of 4 V the current in the feedback resistor will not exceed 1 mA. A possible choice: R1 = 4 kΩ, R2 = 1 kΩ, and Rf = 4 kΩ
