Tool/software:
Dear All,
I try to import LMH6622 PSICE .MOD file to my 9th order Butterworth Sallen-Key filter simulation schematic in TINA environment (Version 9.3.200.277 SF-TI).
I've followed all steps in SLVA527–June 2012 "Importing a SPICE NetList Into TINA9-TI" guideline. I have tried two methods to import PSICE file as I explained below.
1) I copied all .MOD file text content into Netlist Editor and compiled model file succesfully. And then I saved it in .CIR format.
2) I used New Macro Wizard interface and selected .MOD file. I followed all steps to create macro file and successfully generated .TSM file w/o any error/warning.
I used TI Filter Pro application to calculate passive component values of my filter circuit. After I drew filter schematic design in TINA (by using Insert->Macro->LMH6622.TSM), I checked component details, and saw related .MOD file directory was correct. I ran AC analysis simulation. And at this point I got unexpected Gain/Frequency plot as below.
I use dual supply (+/-5V) for the op-amp and don't think I violate GBW and slew rate specs of the op-amp in my design. My filter has Fc=2.2MHz, Sine Wave Input Vp-p=2V.
I've also set Analysis Parameters as below.
Could anyone tell me/help me with what could be wrong in my PSPICE model file integration/importing process?
Best regards & Thanks,
Batu
