Hello,I am trying to build a driver for my YIG shown below.

I have made a AC and time domain plots.
I know that in feedback theory i need 0dB gain and phase shift of 180 degrees.
How can i see this oscilation condition in my AC plot?
I dont have even 0dB in the plot.
In the AC plots?

sesitivity: 450 KHz/mA
3dB bandwidth 2.2MHz
resistance 2Ohm
inductance 1.5uH

Where are you looking at the amplitude and phase response?

?

Have you simulated the entire PLL circuit?
