I'm stuck on a question that I have no understanding of and I was wondering if someone could help.
When vin(t)=2.5+cos(2*pi*100*t) for 0<t<30
Use the small signal model of the diode to predict the output voltage of the circuit. Assume the opamp is ideal and R = 2000ohms, Is = 10^16 A, Vt = 0.0252 V. The diode current is given by the equation iD = Is(e^(vd/Vt)  1).
How would I go about doing this? I don't understand how I can use the small signal model to do this, because I can't seem to understand what exactly the small signal model is trying to achieve and what equations are relevant because my textbook is a little too flaky about it (at least for me) and I also tried Wikipedia in the hopes that it would have something that might help, but no luck there. Since the small signal model involves a current  voltage graph, I don't get what part of it would give me the answer I need to get the sinusoidal output voltage for the answer. I also don't know how to use the small signal model.
Can anyone help please?
