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

  • Another way is you can change the range of the Y-axis so that both plots are of the same scale, then you would notice that "small" difference in the plots.

    But, again, to reiterate, please refrain from using the LTspice XVII version as the support for this version has ceased already.

    Best Regards,
