It is known R4=R5=1.2k. My task is to calculate amplitude of oscillations at v0:

Opamp and diodes are ideal.

I did analysis of circuit without amplitude stabilization and I got oscillation frequency, but I cant figure out how diodes stabilize amplitude in this circuit.

Any sugestion?

Thanks in advance.

Edit: I simulated this circuit in Multisim:

It looks like amplitude is 8.954*sqrt(2)V.

One strange thing: how can voltage on diode be 3.409V ??

I was thought that when diode is direct biased, voltage drop on it is about 0.7V.
