I’ll ask you a question.
When I simulate the circuit diagram above, an error occurs.
Please advise to make the simulation go well.

You are using an LTSPICE model for the the LT1006 opamp which is not compatible to ngspice. These models use an internal device A1...ota... which is specific to LTSPICE only, and which causes the error message.

Unfortunately there is currently no solution toi this problem, you may use a different opamp.

thank you.
I used an AD820ANZ operational amplifier and it worked properly.
appreciate.
