LTspice-24.0.12 Simulate different waveform with previous version LTspiceXVII

Category: Software
Product Number: ltspice
Software Version: LTspice 24.0.12

Hi,

I am new to LTspice, but I recently simulated a simple circuit with the new version of LTspice 24.0.12 and I got quite different result with the previous XVII.

I tried to perform .AC simulation with the 24.0.12 and I got below pic, the gain is going up from around 20khz. 

LTspice 24.0.12 .ac simulation

It is not the same with the simulating of XVII, here I also attach the pic of XVII . With the same schematic, the gain is going down from around 20khz in XVII. 

LTspice XVII

I have no idea why this happen. Could anyone help me? Appreciate for it.

Here is the .asc file .InvertingAmplifierCircuit.asc

  • Hi  ,

    I understand your concern, but we had already ceased any support on the LTspice version XVII, the updated models are already on the latest version which is v24.

    As much as I want to address this concern, trying to investigate in XVII is not practical as we don't update the contents of those anymore.

    The results you are seeing on v24 is the updated version as per checking with its revision history.

    Best Regards.
