Re: Gain and amplitude of a LC oscillator with a non ideal OPAMP
Yes, it is really a poor quality OPAMP for this exercise.
I suppose the purpose is to is to understand the effect of the intrinsic "imperfection".
Also, I think the OPAMP here is implementing a negative impedance, to compensate for the energy loss of the LC circuit.
This because in reality the LC section behaves as C//L//R, and so the oscillation get smaller and smaller until all the energy has dissipated.
This is a theoretical problem, and I don't know how to solve this.
