In the following circuit I have to find the output voltage, Vo, related to the input voltage, Vin. We assume that both diodes, D1 and D2, are the same and have a 0.7 V drop when they conduct and op-amps are ideal.
I am thinking that at start, before any input is applied, both D1 and D2 are reversed biased and no current flows in the circuit. When a positive input is applied (Vin > 0), op-amp 1 will immediately saturate at the negative supply (V -> V+), which means that V' will be negative and D1 will conduct when D2 will be reversed biased.
On the other hand, when a negative input is applied (Vin < 0) opamp 1 will immediately saturate at the positive supply (V- < V+) which means that V' will be positive and D2 will conduct when D1 will be reversed biased. Then, in both cases, we will have a circuit with closed loop op-amps with negative feedbacks. Thus, by using Kirchhoff's law I can define the output voltage related to the input voltage knowing that no currents flow in or out of the inputs of the op-amps.
Is this process right?
