I very much agree that the professor is an idiot. You said that the part that is kept constant becomes the dc gain, and in that graph, 100dB seems to be constant. But 100dB itself can't be gain, so please tell me what additional steps should be performed through ltspice to get dc gain. I've...

I'm sorry, but I don't have data on the schematic. Because of the professor's instructions, I only have the netlist, and I have to run the simulation through it and find out the results. The result of the ac simulation is like the picture, and I don't know how to find the dc gain here.

I use this netlist and simulation result came out as shown. I need to find the dc gain here and circuit diagram, but I'm not sure how. I would be very grateful if you could give me the answer.

You can probably replace it with an equivalent independent voltage source. I need to observe the vo value according to the change of the vid, so I hope I can solve the vid.

sorry. vin1 is upper amp's + input and vin2 is lower amp's + input. The does 1/2vid can't be configured as vcvs in ltspice?

As you can see in the picture, 1/2vid is entered in each of Vin1 and Vin2 on the left. Assuming Vcm is 0, I need to configure this circuit with ltspice, but I am not sure how to configure this vcvs. I'd appreciate it if you could tell me how.
