Question
Assuming that the op-amps are ideal, what is the nodal voltage Vo1, Vo2, and Vout, respectively?
R1=1kΩ, R2=7kΩ, R3=8.7kΩ, V1=0.2V, V2=0.1V
Notes:
- This is a cascaded amplifier
- All op-amps are in negative feedback so positive and negative inputs are equal
- Use superposition (one of the op-amp is in basic negative feedback while the other is a non-inverting amplifier)
